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).

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.

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.

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. While this loses some of the generic helper routines for inserting/moving/removing records it also solves some of the one off bugs in the original code and makes it easier to verify.

From: Dave Chinner <dgc@sgi.com> The most complicated part here is the lastrec tracking for the alloc btree. Most logic is in the update_lastrec method which has to do some hopefully good enough dirty magic to maintain it. [hch: split out from bigger patch and a rework of the lastrec logic] SGI-PV: 985583 SGI-Modid: xfs-linux-melb:xfs-kern:32194a Signed-off-by: NChristoph Hellwig <hch@infradead.org> Signed-off-by: NLachlan McIlroy <lachlan@sgi.com> Signed-off-by: NBill O'Donnell <billodo@sgi.com> Signed-off-by: NDavid Chinner <david@fromorbit.com>

From: Dave Chinner <dgc@sgi.com> Because this is the first major generic btree routine this patch includes some infrastrucure, first a few routines to deal with a btree block that can be either in short or long form, second xfs_btree_read_buf_block, which is the new central routine to read a btree block given a cursor, and third the new xfs_btree_ptr_addr routine to calculate the address for a given btree pointer record.

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.

This macro is unused an all other acros in this family operate on native types, so we most likely won't grow a user either. SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:29846a Signed-off-by: NLachlan McIlroy <lachlan@sgi.com> Signed-off-by: NTim Shimmin <tes@sgi.com>

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).

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!
