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.
