2012-12-16Merge tag 'balancenuma-v11' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma Pull Automatic NUMA Balancing bare-bones from Mel Gorman: "There are three implementations for NUMA balancing, this tree (balancenuma), numacore which has been developed in tip/master and autonuma which is in aa.git. In almost all respects balancenuma is the dumbest of the three because its main impact is on the VM side with no attempt to be smart about scheduling. In the interest of getting the ball rolling, it would be desirable to see this much merged for 3.8 with the view to building scheduler smarts on top and adapting the VM where required for 3.9. The most recent set of comparisons available from different people are mel: https://lkml.org/lkml/2012/12/9/108 mingo: https://lkml.org/lkml/2012/12/7/331 tglx: https://lkml.org/lkml/2012/12/10/437 srikar: https://lkml.org/lkml/2012/12/10/397 The results are a mixed bag. In my own tests, balancenuma does reasonably well. It's dumb as rocks and does not regress against mainline. On the other hand, Ingo's tests shows that balancenuma is incapable of converging for this workloads driven by perf which is bad but is potentially explained by the lack of scheduler smarts. Thomas' results show balancenuma improves on mainline but falls far short of numacore or autonuma. Srikar's results indicate we all suffer on a large machine with imbalanced node sizes. My own testing showed that recent numacore results have improved dramatically, particularly in the last week but not universally. We've butted heads heavily on system CPU usage and high levels of migration even when it shows that overall performance is better. There are also cases where it regresses. Of interest is that for specjbb in some configurations it will regress for lower numbers of warehouses and show gains for higher numbers which is not reported by the tool by default and sometimes missed in treports. Recently I reported for numacore that the JVM was crashing with NullPointerExceptions but currently it's unclear what the source of this problem is. Initially I thought it was in how numacore batch handles PTEs but I'm no longer think this is the case. It's possible numacore is just able to trigger it due to higher rates of migration. These reports were quite late in the cycle so I/we would like to start with this tree as it contains much of the code we can agree on and has not changed significantly over the last 2-3 weeks." * tag 'balancenuma-v11' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma: (50 commits) mm/rmap, migration: Make rmap_walk_anon() and try_to_unmap_anon() more scalable mm/rmap: Convert the struct anon_vma::mutex to an rwsem mm: migrate: Account a transhuge page properly when rate limiting mm: numa: Account for failed allocations and isolations as migration failures mm: numa: Add THP migration for the NUMA working set scanning fault case build fix mm: numa: Add THP migration for the NUMA working set scanning fault case. mm: sched: numa: Delay PTE scanning until a task is scheduled on a new node mm: sched: numa: Control enabling and disabling of NUMA balancing if !SCHED_DEBUG mm: sched: numa: Control enabling and disabling of NUMA balancing mm: sched: Adapt the scanning rate if a NUMA hinting fault does not migrate mm: numa: Use a two-stage filter to restrict pages being migrated for unlikely task<->node relationships mm: numa: migrate: Set last_nid on newly allocated page mm: numa: split_huge_page: Transfer last_nid on tail page mm: numa: Introduce last_nid to the page frame sched: numa: Slowly increase the scanning period as NUMA faults are handled mm: numa: Rate limit setting of pte_numa if node is saturated mm: numa: Rate limit the amount of memory that is migrated between nodes mm: numa: Structures for Migrate On Fault per NUMA migration rate limiting mm: numa: Migrate pages handled during a pmd_numa hinting fault mm: numa: Migrate on reference policy ...
2012-12-15Revert "x86-64/efi: Use EFI to deal with platform wall clock (again)"Linus Torvalds
This reverts commit bd52276fa1d4 ("x86-64/efi: Use EFI to deal with platform wall clock (again)"), and the two supporting commits: da5a108d05b4: "x86/kernel: remove tboot 1:1 page table creation code" 185034e72d59: "x86, efi: 1:1 pagetable mapping for virtual EFI calls") as they all depend semantically on commit 53b87cf088e2 ("x86, mm: Include the entire kernel memory map in trampoline_pgd") that got reverted earlier due to the problems it caused. This was pointed out by Yinghai Lu, and verified by me on my Macbook Air that uses EFI. Pointed-out-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending Pull target updates from Nicholas Bellinger: "It has been a very busy development cycle this time around in target land, with the highlights including: - Kill struct se_subsystem_dev, in favor of direct se_device usage (hch) - Simplify reservations code by combining SPC-3 + SCSI-2 support for virtual backends only (hch) - Simplify ALUA code for virtual only backends, and remove left over abstractions (hch) - Pass sense_reason_t as return value for I/O submission path (hch) - Refactor MODE_SENSE emulation to allow for easier addition of new mode pages. (roland) - Add emulation of MODE_SELECT (roland) - Fix bug in handling of ExpStatSN wrap-around (steve) - Fix bug in TMR ABORT_TASK lookup in qla2xxx target (steve) - Add WRITE_SAME w/ UNMAP=0 support for IBLOCK backends (nab) - Convert ib_srpt to use modern target_submit_cmd caller + drop legacy ioctx->kref usage (nab) - Convert ib_srpt to use modern target_submit_tmr caller (nab) - Add link_magic for fabric allow_link destination target_items for symlinks within target_core_fabric_configfs.c code (nab) - Allocate pointers in instead of full structs for config_group->default_groups (sebastian) - Fix 32-bit highmem breakage for FILEIO (sebastian) All told, hch was able to shave off another ~1K LOC by killing the se_subsystem_dev abstraction, along with a number of PR + ALUA simplifications. Also, a nice patch by Roland is the refactoring of MODE_SENSE handling, along with the addition of initial MODE_SELECT emulation support for virtual backends. Sebastian found a long-standing issue wrt to allocation of full config_group instead of pointers for config_group->default_group[] setup in a number of areas, which ends up saving memory with big configurations. He also managed to fix another long-standing BUG wrt to broken 32-bit highmem support within the FILEIO backend driver.

2012-12-15Revert "x86, mm: Include the entire kernel memory map in trampoline_pgd"Linus Torvalds
This reverts commit 53b87cf088e2ea68d7c59619d0214cc15bb76133. It causes odd bootup problems on x86-64. Markus Trippelsdorf gets a repeatable oops, and I see a non-repeatable oops (or constant stream of messages that scroll off too quickly to read) that seems to go away with this commit reverted. So we don't know exactly what is wrong with the commit, but it's definitely problematic, and worth reverting sooner rather than later.

2012-12-14Revert "sched: Update_cfs_shares at period edge"Linus Torvalds
This reverts commit f269ae0469fc882332bdfb5db15d3c1315fe2a10. It turns out it causes a very noticeable interactivity regression with CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a terminal window, while scrolling in a browser - the autogrouping means that the two end up in separate cgroups, and the browser should be smooth as silk despite the high load). Says Paul Turner: "It seems that the update-throttling on the wake-side is reducing the interactive tasks' ability to preempt. While I suspect the right longer term answer here is force these updates only in the cross-cgroup case; this is less trivial. For this release I believe the right answer is either going to be a revert or restore the updates on the enqueue-side."

Merge emailed autofs cleanup/fix patches from Ian Kent * autofs: autofs4 - use simple_empty() for empty directory check autofs4 - dont clear DCACHE_NEED_AUTOMOUNT on rootless mount
2012-12-13autofs4 - use simple_empty() for empty directory checkIan Kent
For direct (and offset) mounts, if an automounted mount is manually umounted the trigger mount dentry can appear non-empty causing it to not trigger mounts. This can also happen if there is a file handle leak in a user space automounting application. This happens because, when a ioctl control file handle is opened on the mount, a cursor dentry is created which causes list_empty() to see the dentry as non-empty. Since there is a case where listing the directory of these dentrys is needed, the use of dcache_dir_*() functions for .open() and .release() is needed. Consequently simple_empty() must be used instead of list_empty() when checking for an empty directory.

2012-12-13autofs4 - dont clear DCACHE_NEED_AUTOMOUNT on rootless mountIan Kent
The DCACHE_NEED_AUTOMOUNT flag is cleared on mount and set on expire for autofs rootless multi-mount dentrys to prevent unnecessary calls to ->d_automount(). Since DCACHE_MANAGE_TRANSIT is always set on autofs dentrys ->d_managed() is always called so the check can be done in ->d_manage() without the need to change the flag. This still avoids unnecessary calls to ->d_automount(), adds negligible overhead and eliminates a seriously ugly check in the expire code.

2012-12-13target/iscsi_target: Add NodeACL tags for initiator group supportAndy Grover
Thanks for reviews, looking a lot better. ---- 8< ---- Initiator access config could be easier. The way other storage vendors have addressed this is to support initiator groups: the admin adds initiator WWNs to the group, and then LUN permissions can be granted for the entire group at once. Instead of changing ktarget's configfs interface, this patch keeps the configfs interface per-initiator-wwn and just adds a 'tag' field for each. This should be enough for user tools like targetcli to group initiator ACLs and sync their configurations. acl_tag is not used internally, but needs to be kept in configfs so that all user tools can avoid dependencies on each other. Code tested to work, although userspace pieces still to be implemented. Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

Pull networking fixes from David Miller: "A pile of fixes in response to yesterday's big merge. The SCTP HMAC thing hasn't been addressed yet, I'll take care of that myself if Neil and Vlad don't show signs of life by tomorrow. 1) Use after free of SKB in tuntap code. Fix by Eric Dumazet, reported by Dave Jones. 2) NFC LLCP code emits annoying kernel log message, triggerable by the user. From Dave Jones. 3) Fix several endianness bugs noticed by sparse in the bridging code, from Stephen Hemminger. 4) Ipv6 NDISC code doesn't take padding into account properly, fix from YOSHIFUJI Hideaki. 5) Add missing docs to ethtool_flow_ext struct, from Yan Burman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: bridge: fix icmpv6 endian bug and other sparse warnings net: ethool: Document struct ethtool_flow_ext ndisc: Fix padding error in link-layer address option. tuntap: dont use skb after netif_rx_ni(skb) nfc: remove noisy message from llcp_sock_sendmsg
2012-12-13Merge branch 'akpm' (Andrew's patch-bomb)Linus Torvalds
Merge misc VM changes from Andrew Morton: "The rest of most-of-MM. The other MM bits await a slab merge. This patch includes the addition of a huge zero_page. Not a performance boost but it an save large amounts of physical memory in some situations. Also a bunch of Fujitsu engineers are working on memory hotplug. Which, as it turns out, was badly broken. About half of their patches are included here; the remainder are 3.8 material." However, this merge disables CONFIG_MOVABLE_NODE, which was totally broken. We don't add new features with "default y", nor do we add Kconfig questions that are incomprehensible to most people without any help text. Does the feature even make sense without compaction or memory hotplug? * akpm: (54 commits) mm/bootmem.c: remove unused wrapper function reserve_bootmem_generic() mm/memory.c: remove unused code from do_wp_page() asm-generic, mm: pgtable: consolidate zero page helpers mm/hugetlb.c: fix warning on freeing hwpoisoned hugepage hwpoison, hugetlbfs: fix RSS-counter warning hwpoison, hugetlbfs: fix "bad pmd" warning in unmapping hwpoisoned hugepage mm: protect against concurrent vma expansion memcg: do not check for mm in __mem_cgroup_count_vm_event tmpfs: support SEEK_DATA and SEEK_HOLE (reprise) mm: provide more accurate estimation of pages occupied by memmap fs/buffer.c: remove redundant initialization in alloc_page_buffers() fs/buffer.c: do not inline exported function writeback: fix a typo in comment mm: introduce new field "managed_pages" to struct zone mm, oom: remove statically defined arch functions of same name mm, oom: remove redundant sleep in pagefault oom handler mm, oom: cleanup pagefault oom handler memory_hotplug: allow online/offline memory to result movable node numa: add CONFIG_MOVABLE_NODE for movable-dedicated node mm, memcg: avoid unnecessary function call when memcg is disabled ...
