move inode tracing out of xfs_vnode.

2008-12-04T04:39:25Z

Move the inode tracing into xfs_iget.c / xfs_inode.h and kill xfs_vnode.c now that it's empty. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Chinner Signed-off-by: Niv Sardi

move vn_iowait / vn_iowake into xfs_aops.c

2008-12-04T04:39:24Z

The whole machinery to wait on I/O completion is related to the I/O path and should be there instead of in xfs_vnode.c. Also give the functions more descriptive names. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Chinner Signed-off-by: Niv Sardi

kill vn_ioerror

2008-12-04T04:39:24Z

There's just one caller of this helper, and it's much cleaner to just merge the xfs_do_force_shutdown call into it. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Chinner Signed-off-by: Niv Sardi

[XFS] Combine the XFS and Linux inodes

2008-10-30T06:36:14Z

To avoid issues with different lifecycles of XFS and Linux inodes, embedd the linux inode inside the XFS inode. This means that the linux inode has the same lifecycle as the XFS inode, even when it has been released by the OS. XFS inodes don't live much longer than this (a short stint in reclaim at most), so there isn't significant memory usage penalties here. Version 3 o kill xfs_icount() Version 2 o remove unused commented out code from xfs_iget(). o kill useless cast in VFS_I() SGI-PV: 988141 SGI-Modid: xfs-linux-melb:xfs-kern:32323a Signed-off-by: David Chinner Signed-off-by: Lachlan McIlroy Signed-off-by: Christoph Hellwig

[XFS] fix instant oops with tracing enabled

2008-10-30T06:21:10Z

We can only read inode->i_count if the inode is actually there and not a NULL pointer. This was introduced in one of the recent sync patches. SGI-PV: 988255 SGI-Modid: xfs-linux-melb:xfs-kern:32315a Signed-off-by: Christoph Hellwig Signed-off-by: Lachlan McIlroy

[XFS] Use struct inodes instead of vnodes to kill vn_grab

2008-10-30T06:15:03Z

With the sync code relocated to the linux-2.6 directory we can use struct inodes directly. If we do the same thing for the quota release code, we can remove vn_grab altogether. While here, convert the VN_BAD() checks to is_bad_inode() so we can remove vnodes entirely from this code.

[XFS] clean up stale references to semaphores

2008-08-13T06:34:31Z

A lot of code has been converted away from semaphores, but there are still comments that reference semaphore behaviour. The log code is the worst offender. Update the comments to reflect what the code really does now. SGI-PV: 981498 SGI-Modid: xfs-linux-melb:xfs-kern:31814a Signed-off-by: David Chinner Signed-off-by: Lachlan McIlroy

[XFS] kill bhv_vnode_t

2008-08-13T06:22:40Z

All remaining bhv_vnode_t instance are in code that's more or less Linux specific. (Well, for xfs_acl.c that could be argued, but that code is on the removal list, too). So just do an s/bhv_vnode_t/struct inode/ over the whole tree. We can clean up variable naming and some useless helpers later.

[XFS] implement IHOLD/IRELE directly

2008-08-13T06:13:45Z

Now that all direct calls to VN_HOLD/VN_RELE are gone we can implement IHOLD/IRELE directly. For the IHOLD case also replace igrab with a direct increment of i_count because we are guaranteed to already have a live and referenced inode by the VFS. Also remove the vn_hold statistic because it's been rather meaningless for some time with most references done by other callers.

[XFS] kill vn_to_inode

2008-08-13T06:12:05Z

bhv_vnode_t is just a typedef for struct inode, so there's no need for a helper to convert between the two. SGI-PV: 981498 SGI-Modid: xfs-linux-melb:xfs-kern:31761a Signed-off-by: Christoph Hellwig Signed-off-by: Lachlan McIlroy
