The core kernel uses vfs_getattr to look at the inode size and similar attributes, so there is no need to keep i_size uptodate for directories or special files. This means we can remove xfs_validate_fields because the I/O path already keeps i_size uptodate for regular files.

xfs_remove and xfs_rmdir are almost the same with a little more work performed in xfs_rmdir due to the . and .. entries. This patch merges xfs_rmdir into xfs_remove and performs these actions conditionally. Also clean up the error handling which was a nightmare in both versions before.

Use the generic set, get and removexattr methods and supply the s_xattr array with fine-grained handlers. All XFS/Linux highlevel attr handling is rewritten from scratch and placed into fs/xfs/linux-2.6/xfs_xattr.c so that it's separated from the generic low-level code.

The vfs_unlink/d_delete functionality in the Linux VFS make the dentry negative if it is the only inode being referenced.

This implements the code to store the actual filename found during a lookup in the dentry cache and to avoid multiple entries in the dcache pointing to the same inode. To avoid polluting the dcache, we implement a new directory inode operations for lookup. xfs_vn_ci_lookup() stores the correct case name in the dcache. The "actual name" is only allocated and returned for a case- insensitive match and not an actual match. Another unusual interaction with the dcache is not storing negative dentries like other filesystems doing a d_add(dentry, NULL) when an ENOENT is returned. During the VFS lookup, if a dentry returned has no inode, dput is called and ENOENT is returned. By not doing a d_add, this actually removes it completely from the dcache to be reused. create/rename have to be modified to support unhashed dentries being passed in.

->rename already gets the target inode passed if it exits. Pass it down to xfs_rename so that we can avoid looking it up again. Also simplify locking as the first lock section in xfs_rename can go away now: the isdir is an invariant over the lifetime of the inode, and new_parent and the nlink check are namespace topology protected by i_mutex in the VFS. The projid check needs to move into the second lock section anyway to not be racy. Also kill the now unused xfs_dir_lookup_int and remove the now-unused first_locked argumet to xfs_lock_inodes.

Use XFS_IS_REALTIME_INODE in more places, and #define it to 0 if CONFIG_XFS_RT is off. This should be safe because mount checks in xfs_rtmount_init: so if we get mounted w/o CONFIG_XFS_RT, no realtime inodes should be encountered after that. Defining XFS_IS_REALTIME_INODE to 0 saves a bit of stack space, presumeably gcc can optimize around the various "if (0)" type checks: xfs_alloc_file_space -8 xfs_bmap_adjacent -16 xfs_bmapi -8 xfs_bmap_rtalloc -16 xfs_bunmapi -28 xfs_free_file_space -64 xfs_imap +8 <-- ? hmm. xfs_iomap_write_direct -12 xfs_qm_dqusage_adjust -4 xfs_qm_vop_chown_reserve -4 SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:30014a Signed-off-by: NEric Sandeen <sandeen@sandeen.net> Signed-off-by: NDavid Chinner <dgc@sgi.com> Signed-off-by: NLachlan McIlroy <lachlan@sgi.com>

The log force added in xfs_iget_core() has been a performance issue since it was introduced for tight loops that allocate then unlink a single file. under heavy writeback, this can introduce unnecessary latency due tothe log I/o getting stuck behind bulk data writes. Fix this latency problem by avoinding the need for the log force by moving the place we mark linux inode dirty to the transaction commit rather than on transaction completion. This also closes a potential hole in the sync code where a linux inode is not dirty between the time it is modified and the time the log buffer has been written to disk.

This was broken by my '[XFS] simplify xfs_create/mknod/symlink prototype', which assigned the re-shuffled ondisk dev_t back to the rdev variable in xfs_vn_mknod. Because of that i_rdev is set to the ondisk dev_t instead of the linux dev_t later down the function. Fortunately the fix for it is trivial: we can just remove the assignment because xfs_revalidate_inode has done the proper job before unlocking the inode.
