The code was fixed as a result of committing the huge patch series that removed bufferheads from the XFS IO path. i.e. the bug went away because of other changes that addressed the root cause, not because we committed a change that specifically fixed the bug. Most likely it was this commit in the middle of the series to remove bufferhead dependencies in xfs_aops_discard_page() that solved the problem. e2ac836307e3 ("xfs: simplify xfs_bmap_punch_delalloc_range") -Dave. -- Dave Chinner david@fromorbit.com
