* [XFS] Fix CI lookup in leaf-form directoriesBarry Naujok2008-07-281-24/+25

* [XFS] Return case-insensitive match for dentry cacheBarry Naujok2008-07-281-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [XFS] Add op_flags field and helpers to xfs_da_argsBarry Naujok2008-07-281-7/+8
| | | | | | | | | | | | | | | | The end of the xfs_da_args structure has 4 unsigned char fields for true/false information on directory and attr operations using the xfs_da_args structure. The following converts these 4 into a op_flags field that uses the first 4 bits for these fields and allows expansion for future operation information (eg. case-insensitive lookup request).

* [XFS] Name operation vector for hash and compareBarry Naujok2008-07-281-17/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds two pieces of functionality for the basis of case-insensitive support in XFS: 1. A comparison result enumerated type: xfs_dacmp. It represents an exact match, case-insensitive match or no match at all. This patch only implements different and exact results. 2. xfs_nameops vector for specifying how to perform the hash generation of filenames and comparision methods. In this patch the hash vector points to the existing xfs_da_hashname function and the comparison method does a length compare, and if the same, does a memcmp and return the xfs_dacmp result. All filename functions that use the hash (create, lookup remove, rename, etc) now use the xfs_nameops.hashname function and all directory lookup functions also use the xfs_nameops.compname function. The lookup functions also handle case-insensitive results even though the default comparison function cannot return that. And important aspect of the lookup functions is that an exact match always has precedence over a case-insensitive. So while a case-insensitive match is found, we have to keep looking just in case there is an exact match. In the meantime, the info for the first case-insensitive match is retained if no exact match is found.

* [XFS] Put the correct offset in dirent d_offLachlan McIlroy2007-12-181-1/+1
| | | | | | | | | | | | | | | | The recent filldir regression fix was not putting the correct d_off in each dirent. This was resulting in incorrect cookies being passed to dmapi ioctls and the wrong offset appearing in the dirents. readdir was unaffected as the filp->f_pos was being updated with the correct offset and this was being written into the last dirent in each buffer. Fix the XFS code to do the right thing.

* [XFS] use filldir internallyChristoph Hellwig2007-10-151-46/+30
| | | | | | | | | | | | | | | | | | | | | | | | | Currently xfs has a rather complicated internal scheme to allow for different directory formats in IRIX. This patch rips all code related to this out and pushes useage of the Linux filldir callback into the lowlevel directory code. This does not make the code any less portable because filldir can be used to create dirents of all possible variations (including the IRIX ones as proved by the IRIX binary emulation code under arch/mips/). This patch get rid of an unessecary copy in the readdir path, about 400 lines of code and one of the last two users of the uio structure. This version is updated to deal with dmapi aswell which greatly simplifies the get_dirattrs code. The dmapi part has been tested using the get_dirattrs tools from the xfstest dmapi suite1 with various small and large directories.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
