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.

XFS inodes are dynamically allocated on demand, rather than being allocated at mkfs time. Chunks of 64 inodes are allocated at once, but they are never freed. Over time, this can lead to filesystem fragmentation, clusters of inodes and the btrees which point at them can be scattered around the system. By freeing clusters as they are emptied, we will reduce fragmentation of the free space after removing files. This in turn will allow us to make better placement decisions when repopulating a filesystem. The XFSMNT_IDELETE mount option enables freeing clusters when they get empty. Unfortunately a side effect of freeing inode clusters is that the inode generation numbers of such inodes would be reset to zero when the cluster is reclaimed. This is a problem in particular for a DMAPI enabled filesystem as the the DMAPI handles need to be unique and persistent in time. An unique DMAPI handle is built with the help of the inode generation number. When the last one is prematurely reset by an inode cluster reclaim, there is a high probability of different generation inodes to end up having identical DMAPI handles. To avoid the problem with identical DMAPI handles, the XFSMNT_IDELETE mount option should be set as default, only if the filesystem is not mounted with XFSMNT_DMAPI.

One of the perpetual scaling problems XFS has is indexing it's incore inodes. We currently uses hashes and the default hash sizes chosen can only ever be a tradeoff between memory consumption and the maximum realistic size of the cache. As a result, anyone who has millions of inodes cached on a filesystem needs to tunes the size of the cache via the ihashsize mount option to allow decent scalability with inode cache operations. A further problem is the separate inode cluster hash, whose size is based on the ihashsize but is smaller, and so under certain conditions (sparse cluster cache population) this can become a limitation long before the inode hash is causing issues. The following patchset removes the inode hash and cluster hash and replaces them with radix trees to avoid the scalability limitations of the hashes. It also reduces the size of the inodes by 3 pointers....

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.

Creates a new xfs_dsb_t that is __be annotated and keeps xfs_sb_t for the incore one. xfs_xlatesb is renamed to xfs_sb_to_disk and only handles the incore -> disk conversion. A new helper xfs_sb_from_disk handles the other direction and doesn't need the slightly hacky table-driven approach because we only ever read the full sb from disk. The handling of shared r/o filesystems has been buggy on little endian system and fixing this required shuffling around of some code in that area.

Biggest bit is duplicating the dinode structure so we have one annotated for native endianess and one for disk endianess. The other significant change is that xfs_xlate_dinode_core is split into one helper per direction to allow for proper annotations, everything else is trivial. As a sidenode splitting out the incore dinode means we can move it into xfs_inode.h in a later patch and severely improving on the include hell in xfs.

This reverts commit b394e43e. Lachlan McIlroy says: It tried to fix an issue where log replay is replaying an inode cluster initialisation transaction that should not be replayed because the inode cluster on disk is more up to date. Since we don't log file sizes (we rely on inode flushing to get them to disk) then we can't just replay all the transations in the log and expect the inode to be completely restored. We lose file size updates. Unfortunately this fix is causing more (serious) problems than it is fixing.

The new xlog_recover_do_reg_buffer checks call be16_to_cpu on di_gen which is a 32bit value so sparse rightly complains. Fortunately the warning is harmless because we don't care for the value, but only whether it's non-NULL. Due to that fact we can simply kill the endian swaps on this and the previous di_mode check entirely.

Then when we converted hsize "back" to nr of elements (the division line) hsize went to 0.
