-Subject: xfs: revert "xfs: fix rmap key and record comparison functions"
-
-This reverts commit 6ff646b2ceb0eec916101877f38da0b73e3a5b7f.
-
-Your maintainer committed a major braino in the rmap code by adding the
-attr fork, bmbt, and unwritten extent usage bits into rmap record key
-comparisons.  While XFS uses the usage bits *in the rmap records* for
-cross-referencing metadata in xfs_scrub and xfs_repair, it only needs
-the owner and offset information to distinguish between reverse mappings
-of the same physical extent into the data fork of a file at multiple
-offsets.  The other bits are not important for key comparisons for index
-lookups, and never have been.
-
-Eric Sandeen reports that this causes regressions in generic/299, so
-undo this patch before it does more damage.
