2008-07-28[XFS] Now that xfs_setattr is only used for attributes set from ->setattrChristoph Hellwig
it can be switched to take struct iattr directly and thus simplify the implementation greatly. Also rename the ATTR_ flags to XFS_ATTR_ to not conflict with the ATTR_ flags used by the VFS.

2008-07-28[XFS] Merge xfs_rmdir into xfs_removeChristoph Hellwig
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.

2008-07-28[XFS] Return case-insensitive match for dentry cacheBarry Naujok
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.

2008-05-23[XFS] Fix fsync() b0rkage.David Chinner
xfs_fsync() fails to wait for data I/O completion before checking if the inode is dirty or clean to decide whether to log the inode or not. This misses inode size updates when the data flushed by the fsync() is extending the file. Hence, like fdatasync(), we need to wait for I/o completion first, then check the inode for cleanliness. Doing so makes the behaviour of xfs_fsync() identical for fsync and fdatasync and we *always* use synchronous semantics if the inode is dirty. Therefore also kill the differences and remove the unused flags from the xfs_fsync function and callers.

2008-04-29[XFS] remove manual lookup from xfs_rename and simplify lockingChristoph Hellwig
->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.

2008-04-29[XFS] kill xfs_getattrChristoph Hellwig
It's currently used by the ACL code to read di_mode/di_uid, but these are simple 32bit scalar values we can just read directly without locking.

2008-02-07[XFS] use generic_permissionChristoph Hellwig
Now that all direct caller of xfs_iaccess are gone we can kill xfs_iaccess and xfs_access and just use generic_permission with a check_acl callback. This is required for the per-mount read-only patchset in -mm to work properly with XFS.

- merge xfs_fid2 into it's only caller xfs_dm_inode_to_fh. - remove xfs_vget and opencode it in the two callers, simplifying both of them by avoiding the awkward calling convetion. - assign directly to the dm_fid_t members in various places in the dmapi code instead of casting them to xfs_fid_t first (which is identical to dm_fid_t) SGI-PV: 974747 SGI-Modid: xfs-linux-melb:xfs-kern:30258a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Vlad Apostolov <vapo@sgi.com> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
2007-10-19[XFS] cleanup fid types messChristoph Hellwig
Currently XFs has three different fid types: struct fid, struct xfs_fid and struct xfs_fid2 with hte latter two beeing identicaly and the first one beeing the same size but an unstructured array with the same size. This patch consolidates all this to alway uuse struct xfs_fid. This patch is required for an upcoming patch series from me that revamps the nfs exporting code and introduces a Linux-wide struct fid.

2007-10-16[XFS] simplify xfs_create/mknod/symlink prototypeChristoph Hellwig
Simplify the prototype for xfs_create/xfs_mkdir/xfs_symlink by not passing down a bhv_vattr_t that just hogs stack space. Instead pass down the mode in a mode_t and in case of xfs_create the rdev as a scalar type as well.

2007-10-15[XFS] decontaminate vnode operations from behavior detailsChristoph Hellwig
All vnode ops now take struct xfs_inode pointers and the behaviour related glue is split out into methods of it's own. This required fixing xfs_create/mkdir/symlink to not mess with the inode pointer but rather use a separate boolean for error handling. Thanks to Dave Chinner for that fix.
