From 60197e8df364df326dcbb987519f367ad0ee1a11 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 30 Oct 2008 17:11:19 +1100 Subject: [XFS] 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.

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.

All sizeof operations on the dinode_core either really wanted the icdinode and are switched to that one, or had already added the size of the agi unlinked list pointer. Later both will be replaced with helpers once we get the larger CRC-enabled dinode. Removing the data and attribute fork unions also has the advantage that xfs_dinode.h doesn't need to pull in every header under the sun. While we're at it also add some more comments describing the dinode structure.
