2011-08-13xfs: remove subdirectoriesChristoph Hellwig38-16527/+0
Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the annoying subdirectories in the XFS source code. Besides the large amount of file rename the only changes are to the Makefile, a few files including headers with the subdirectory prefix, and the binary sysctl compat code that includes a header under fs/xfs/ from kernel/.

2011-07-27xfs: optimize the negative xattr cachingChristoph Hellwig1-2/+7
Since the addition of file capabilities every write needs to read xattrs to check if we have any capabilities to clear. In Linux 3.0 Andi Kleen added a flag to cache the fact that we do not have any attributes on an inode. Make sure to already mark a file as not having any attributes when reading it from disk in case it doesn't even have an attribute fork. Based on an earlier patch from Andi Kleen.

2011-07-27xfs: prevent against ioend livelocks in xfs_file_fsyncChristoph Hellwig1-0/+2
We need to take some locks to prevent new ioends from coming in when we wait for all existing ones to go away. Up to Linux 3.0 that was done using the i_mutex held by the VFS fsync code, but now that we are called without it we need to take care of it ourselves. Use the I/O lock instead of i_mutex just like we do in other places. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>
2011-07-27xfs: flag all buffers as metadataChristoph Hellwig1-0/+3
Now that REQ_META bios aren't treated specially in the CFQ I/O schedule anymore, we can tag all buffers as metadata to make blktrace traces more meaningful. Note that we use buffers also to zero out partial blocks in the preallocation / hole punching code, and while they operate on data blocks the zeros written certainly aren't data. I think this case is borderline metadata enough to not bother special casing it. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>

2011-07-25vfs: move ACL cache lookup into generic codeLinus Torvalds1-6/+2
This moves logic for checking the cached ACL values from low-level filesystems into generic code. The end result is a streamlined ACL check that doesn't need to load the inode->i_op->check_acl pointer at all for the common cached case. The filesystems also don't need to check for a non-blocking RCU walk case in their acl_check() functions, because that is all handled at a VFS layer.

The fsync prototype change commit 02c24a82187d accidentally overwrote the ssize_t return value of xfs_file_aio_write with 0 for SYNC type writes.

2011-07-21fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlersJosef Bacik1-9/+8
Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

2011-07-21fs: move inode_dio_done to the end_io handlerChristoph Hellwig1-0/+3
For filesystems that delay their end_io processing we should keep our i_dio_count until the the processing is done. Enable this by moving the inode_dio_done call to the end_io handler if one exist. Note that the actual move to the workqueue for ext4 and XFS is not done in this patch yet, but left to the filesystem maintainers. At least for XFS it's not needed yet either as XFS has an internal equivalent to i_dio_count. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-21xfs: make use of new shrinker callout for the inode cacheDave Chinner3-56/+46
Convert the inode reclaim shrinker to use the new per-sb shrinker operations. This allows much bigger reclaim batches to be used, and allows the XFS inode cache to be shrunk in proportion with the VFS dentry and inode caches. This avoids the problem of the VFS caches being shrunk significantly before the XFS inode cache is shrunk resulting in imbalances in the caches during reclaim.

2011-07-21xfs: failure mapping nfs fh to inode should return ESTALEJ. Bruce Fields1-2/+2
On xfs exports, nfsd is incorrectly returning ENOENT instead of ESTALE on attempts to use a filehandle of a deleted file (spotted with pynfs test PUTFH3). The ENOENT was coming from xfs_iget. (It's tempting to wonder whether we should just map all xfs_iget errors to ESTALE, but I don't believe so--xfs_iget can also return ENOMEM at least, which we wouldn't want mapped to ESTALE.) While we're at it, the other return of ENOENT in xfs_nfs_get_inode() also looks wrong. Signed-off-by: J. Bruce Fields <bfields@redhat.com> Signed-off-by: Alex Elder <aelder@sgi.com>
