From 33479e0542df066fb0b47df18780e93bfe6e0dc5 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 8 Oct 2012 21:56:11 +1100 Subject: xfs: remove xfs_iget.c The inode cache functions remaining in xfs_iget.c can be moved to xfs_icache.c along with the other inode cache functions. This removes all functionality from xfs_iget.c, so the file can simply be removed. This move results in various functions now only having the scope of a single file (e.g. xfs_inode_free()), so clean up all the definitions and exported prototypes in xfs_icache.[ch] and xfs_inode.h appropriately.

Add a helper to consolidate the check. Note that when we remove an inode from the cache (xfs_inactive()), we are required to trim post-EOF blocks even if the inode is marked preallocated or append-only to maintain correct space accounting. The 'force' parameter to xfs_can_free_eofblocks() specifies whether we should ignore the prealloc/append-only status of the inode.

Because each different btree block type requires different verification, add a function to the ops structure that is called from the generic code. Also, propagate the verification callback functions through the readahead functions, and into the external bmap and bulkstat inode readahead code that uses the generic btree buffer read functions.

Hence factor the read verifier functions and add a new write verifier wrapper that is used as the callback. This is done as one large patch for all verifiers rather than one patch per verifier as the change is largely mechanical. This includes hooking up the write verifier via the read verifier function. Hooking up the write verifier for buffers obtained via xfs_trans_get_buf() will be done in a separate patch as that touches code in many different places rather than just the verifier functions.

To separate the verifiers from iodone functions and associate read and write verifiers at the same time, introduce a buffer verifier operations structure to the xfs_buf. This avoids the need for assigning the write verifier, clearing the iodone function and re-running ioend processing in the read verifier, and gets rid of the nasty "b_pre_io" name for the write verifier function pointer. If we ever need to, it will also be easier to add further content specific callbacks to a buffer with an ops structure in place. We also avoid needing to export verifier functions, instead we can simply export the ops structures for those that are needed outside the function they are defined in. This patch also fixes a directory block readahead verifier issue it exposed. This patch also adds ops callbacks to the inode/alloc btree blocks initialised by growfs. These will need more work before they will work with CRCs.
