xfs: vectorise encoding/decoding directory headers
Conversion from on-disk structures to in-core header structures currently relies on magic number checks. If the magic number is wrong, but one of the supported values, we do the wrong thing with the encode/decode operation. Split these functions so that there are discrete operations for the specific directory format we are handling. In doing this, move all the header encode/decode functions to xfs_da_format.c as they are directly manipulating the on-disk format. It should be noted that all the growth in binary size is from xfs_da_format.c - the rest of the code actaully shrinks. text data bss dec hex filename 794490 96802 1096 892388 d9de4 fs/xfs/xfs.o.orig 792986 96802 1096 890884 d9804 fs/xfs/xfs.o.p1 792350 96802 1096 890248 d9588 fs/xfs/xfs.o.p2 789293 96802 1096 887191 d8997 fs/xfs/xfs.o.p3 789005 96802 1096 886903 d8997 fs/xfs/xfs.o.p4 789061 96802 1096 886959 d88af fs/xfs/xfs.o.p5 789733 96802 1096 887631 d8b4f fs/xfs/xfs.o.p6 791421 96802 1096 889319 d91e7 fs/xfs/xfs.o.p7 Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Ben Myers <bpm@sgi.com> Signed-off-by: Ben Myers <bpm@sgi.com>
