2008-10-23[ARM] 5320/1: fix assembly constraints in implementation of do_div()Nicolas Pitre
Those inline assembly segments using the umlal instruction must have the & modifier so to be sure that a purely input register won't alias one of the registers used as input+output. In most cases, the inputs are still used after the outputs are touched, and most binutil versions insist on "rdhi, rdlo and rm must all be different" even for ARMv6+.

2008-10-23proc: fix vma display mismatch between /proc/pid/{maps,smaps}Joe Korty
Commit 4752c369789250eafcd7813e11c8fb689235b0d2 aka "maps4: simplify interdependence of maps and smaps" broke /proc/pid/smaps, causing it to display some vmas twice and other vmas not at all. For example: grep .- /proc/1/smaps >/tmp/smaps; diff /proc/1/maps /tmp/smaps 1 25d24 2 < 7fd7e23aa000-7fd7e23ac000 rw-p 7fd7e23aa000 00:00 0 3 28a28 4 > ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall] The bug has something to do with setting m->version before all the seq_printf's have been performed. show_map was doing this correctly, but show_smap was doing this in the middle of its seq_printf sequence. This patch arranges things so that the setting of m->version in show_smap is also done at the end of its seq_printf sequence. Testing: in addition to the above grep test, for each process I summed up the 'Rss' fields of /proc/pid/smaps and compared that to the 'VmRSS' field of /proc/pid/status. All matched except for Xorg (which has a /dev/mem mapping which Rss accounts for but VmRSS does not). This result gives us some confidence that neither /proc/pid/maps nor /proc/pid/smaps are any longer skipping or double-counting vmas.

2008-10-23[PATCH] fs: add a sanity check in d_freeArjan van de Ven
Hi Al, remember that debug session we did at KS? You suggested this patch back then....

2008-10-23[patch] vfs: make security_inode_setattr() calling consistentMiklos Szeredi
Call security_inode_setattr() consistetly before inode_change_ok(). It doesn't make sense to try to "optimize" the i_op->setattr == NULL case, as most filesystem do define their own setattr function. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
2008-10-23[patch 1/3] FS_MBCACHE: don't needlessly make it built-inAdrian Bunk
Assume you have: - one or more of ext2/3/4 statically built into your kernel - none of these with extended attributes enabled and - want to add onother one of ext2/3/4 modular and with extended attributes enabled then you currently have to reboot to use it since this results in CONFIG_FS_MBCACHE=y. That's not a common issue, but I just ran into it and since there's no reason to get a built-in mbcache in this case this patch fixes it.

2008-10-23[PATCH] move executable checking into ->permission()Miklos Szeredi
For execute permission on a regular files we need to check if file has any execute bits at all, regardless of capabilites. This check is normally performed by generic_permission() but was also added to the case when the filesystem defines its own ->permission() method. In the latter case the filesystem should be responsible for performing this check. Move the check from inode_permission() inside filesystems which are not calling generic_permission(). Create a helper function execute_ok() that returns true if the inode is a directory or if any execute bits are present in i_mode. Also fix up the following code: - coda control file is never executable - sysctl files are never executable - hfs_permission seems broken on MAY_EXEC, remove - hfsplus_permission is eqivalent to generic_permission(), remove Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>

2008-10-23[PATCH] reiserfs: add missing llseek methodChristoph Hellwig
Reiserfs currently doesn't set a llseek method for regular files, which means it will fall back to default_llseek. This means no one can seek beyond 2 Gigabytes on reiserfs, and that there's not protection vs the i_size updates from writers. Signed-off-by: Christoph Hellwig <hch@lst.de>

2008-10-23[PATCH vfs-2.6 6/6] vfs: add LOOKUP_RENAME_TARGET intentOGAWA Hirofumi
This adds LOOKUP_RENAME_TARGET intent for lookup of rename destination. LOOKUP_RENAME_TARGET is going to be used like LOOKUP_CREATE. But since the destination of rename() can be existing directory entry, so it has a difference. Although that difference doesn't matter in my usage, this tells it to user of this intent. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>
2008-10-23[PATCH vfs-2.6 5/6] vfs: remove LOOKUP_PARENT from non LOOKUP_PARENT lookupOGAWA Hirofumi
lookup_hash() with LOOKUP_PARENT is bogus. And this prepares to add new intent on those path. The user of LOOKUP_PARENT intent is nfs only, and it checks whether nd->flags has LOOKUP_CREATE or LOOKUP_OPEN, so the result is same. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>
2008-10-23[PATCH vfs-2.6 4/6] vfs: remove unnecessary fsnotify_d_instantiate()OGAWA Hirofumi

2008-10-23[PATCH vfs-2.6 3/6] vfs: add __d_instantiate() helperOGAWA Hirofumi
This adds __d_instantiate() for users which is already taking dcache_lock, and replace with it. The part of d_add_ci() isn't equivalent. But it should be needed fsnotify_d_instantiate() actually, because the path is to add the inode to negative dentry. fsnotify_d_instantiate() should be called after change from negative to positive.

2008-10-23[PATCH vfs-2.6 2/6] vfs: add d_ancestor()OGAWA Hirofumi
This adds d_ancestor() instead of d_isparent(), then use it. If new_dentry == old_dentry, is_subdir() returns 1, looks strange. "new_dentry == old_dentry" is not subdir obviously. But I'm not checking callers for now, so this keeps current behavior. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>
