2010-03-01GFS2: print glock numbers in hexBob Peterson
This patch changes glock numbers from printing in decimal to hex. Since DLM prints corresponding resource IDs in hex, it makes debugging easier. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2010-03-01GFS2: ordered writes are backwardsDave Chinner
When we queue data buffers for ordered write, the buffers are added to the head of the ordered write list. When the log needs to push these buffers to disk, it also walks the list from the head. The result is that the the ordered buffers are submitted to disk in reverse order. For large writes, this means that whenever the log flushes large streams of reverse sequential order buffers are pushed down into the block layers. The elevators don't handle this particularly well, so IO rates tend to be significantly lower than if the IO was issued in ascending block order. Queue new ordered buffers to the tail of the ordered buffer list to ensure that IO is dispatched in the order it was submitted. This should significantly improve large sequential write speeds. On a disk capable of 85MB/s, speeds increase from 50MB/s to 65MB/s for noop and from 38MB/s to 50MB/s for cfq.

2010-03-01GFS2: Remove loopy umount codeSteven Whitehouse
As a consequence of the previous patch, we can now remove the loop which used to be required due to the circular dependency between the inodes and glocks. Instead we can just invalidate the inodes, and then clear up any glocks which are left. Also we no longer need the rwsem since there is no longer any danger of the inode invalidation calling back into the glock code (and from there back into the inode code). Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2010-03-01GFS2: Metadata address space clean upSteven Whitehouse
Since the start of GFS2, an "extra" inode has been used to store the metadata belonging to each inode. The only reason for using this inode was to have an extra address space, the other fields were unused. This means that the memory usage was rather inefficient. The reason for keeping each inode's metadata in a separate address space is that when glocks are requested on remote nodes, we need to be able to efficiently locate the data and metadata which relating to that glock (inode) in order to sync or sync and invalidate it (depending on the remotely requested lock mode). This patch adds a new type of glock, which has in addition to its normal fields, has an address space. This applies to all inode and rgrp glocks (but to no other glock types which remain as before). As a result, we no longer need to have the second inode. This results in three major improvements: 1. A saving of approx 25% of memory used in caching inodes 2. A removal of the circular dependency between inodes and glocks 3. No confusion between "normal" and "metadata" inodes in super.c Although the first of these is the more immediately apparent, the second is just as important as it now enables a number of clean ups at umount time. Those will be the subject of future patches. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2010-02-26Remove EXPERIMENTAL from NFS_FSCACHEChristian Kujau
There's currently an open Ubuntu bug[0], with the intent to compile NFS_FSCACHE (and possibly AFS_FSCACHE, 9P_FSCACHE) into the standard Ubuntu kernel. However, since *_FSCACHE still depends on EXPERIMENTAL, this won't happen. As Arjan van de Ven pointed out[1], the EXPERIMENTAL flag doesn't mean that much any more, I propose the following patch to fs/nfs/Kconfig. I'd do the same for fs/9p/Kconfig and fs/afs/Kconfig, but as I did not test 9p or AFS, I feel it would not be appropriate for me to remove the flag.

2010-02-26dlm: send reply before bastDavid Teigland
When the lock master processes a successful operation (request, convert, cancel, or unlock), it will process the effects of the change before sending the reply for the operation. The "effects" of the operation are: - blocking callbacks (basts) for any newly granted locks - waiting or converting locks that can now be granted The cast is queued on the local node when the reply from the lock master is received. This means that a lock holder can receive a bast for a lock mode that is doesn't yet know has been granted. Signed-off-by: David Teigland <teigland@redhat.com>

2010-02-24dlm: fix ordering of bast and castDavid Teigland
When both blocking and completion callbacks are queued for lock, the dlm would always deliver the completion callback (cast) first. In some cases the blocking callback (bast) is queued before the cast, though, and should be delivered first. This patch keeps track of the order in which they were queued and delivers them in that order. This patch also keeps track of the granted mode in the last cast and eliminates the following bast if the bast mode is compatible with the preceding cast mode. This happens when a remotely mastered lock is demoted, e.g. EX->NL, in which case the local node queues a cast immediately after sending the demote message. In this way a cast can be queued for a mode, e.g. NL, that makes an in-transit bast extraneous. Signed-off-by: David Teigland <teigland@redhat.com>

2010-02-20CacheFiles: Fix a race in cachefiles_delete_object() vs renameDavid Howells
cachefiles_delete_object() can race with rename. It gets the parent directory of the object it's asked to delete, then locks it - but rename may have changed the object's parent between the get and the completion of the lock. However, if such a circumstance is detected, we abandon our attempt to delete the object - since it's no longer in the index key path, it won't be seen again by lookups of that key. The assumption is that cachefilesd may have culled it by renaming it to the graveyard for later destruction.
