Always use struct xfs_btree_block instead of short / longform structures. Always use the generic xfs_btree_block type instead of the short / long structures. Add XFS_BTREE_SBLOCK_LEN / XFS_BTREE_LBLOCK_LEN defines for the length of a short / long form block. The rationale for this is that we will grow more btree block header variants to support CRCs and other RAS information, and always accessing them through the same datatype with unions for the short / long form pointers makes implementing this much easier. Signed-off-by: Christoph Hellwig <hch@lst.de> Merge of xfs-linux-melb:xfs-kern:32300a by kenmcd. Always use struct xfs_btree_block instead of short / longform structures.

cleanup btree record / key / ptr addressing macros. Replace the generic record / key / ptr addressing macros that use cpp token pasting with simpler macros that do the job for just one given btree type. The new macros lose the cur argument and thus can be used outside the core btree code, but also gain an xfs_mount * argument to allow for checking the CRC flag in the near future. Note that many of these macros aren't actually used in the kernel code, but only in userspace (mostly in xfs_repair).

Cleanup maxrecs calculation. Clean up the way the maximum and minimum records for the btree blocks are calculated. For the alloc and inobt btrees all the values are pre-calculated in xfs_mount_common, and we switch the current loop around the ugly generic macros that use cpp token pasting to generate type names to two small helpers in normal C code. For the bmbt and bmdr trees these helpers also exist, but can be called during runtime, too. Here we also kill various macros dealing with them and inline the logic into the get_minrecs / get_maxrecs / get_dmaxrecs methods in xfs_bmap_btree.c. Note that all these new helpers take an xfs_mount * argument which will be needed to determine the size of a btree block once we add support for extended btree blocks with CRCs and other RAS information.

implement generic xfs_btree_get_rec Not really much reason to make it generic given that it's so small, but this is the last non-method in xfs_alloc_btree.c and xfs_ialloc_btree.c, so it makes the whole btree implementation more structured.

implement generic xfs_btree_delete/delrec Make the btree delete code generic. Based on a patch from David Chinner with lots of changes to follow the original btree implementations more closely.

split up xfs_btree_init_cursor xfs_btree_init_cursor contains close to little shared code for the different btrees and will get even more non-common code in the future. Split it up into one routine per btree type. Because xfs_btree_dup_cursor needs to call the init routine for a generic btree cursor add a new btree operation vector that contains a dup_cursor method that initializes a new cursor based on an existing one. The btree operations vector is based on an idea and code from Dave Chinner and will grow more entries later during this series.

Remove unused arguments from the XFS_BTREE_*_ADDR macros. It makes it incrementally clearer to read the code when the top of a macro spaghetti-pile only receives the 3 arguments it uses, rather than 2 extra ones which are not used. Also when you start pulling this thread out of the sweater (i.e. remove unused args from XFS_BTREE_*_ADDR), a couple other third arms etc fall off too. If they're not used in the macro, then they sometimes don't need to be passed to the function calling the macro either, etc.... Patch provided by Eric Sandeen (sandeen@sandeen.net).
