Subject: Merge tag 'maxrefcount-fixes-6.2_2022-12-01' of git://git.kernel.org/pub/scm/linux... 
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=948961964b2404ea474a3643fc0e1b77c592bb7c;p=linux.git

Merge tag 'maxrefcount-fixes-6.2_2022-12-01' of git://git./linux/kernel/git/djwong/xfs-linux into xfs-6.2-mergeD

xfs: fix broken MAXREFCOUNT handling

This series fixes a bug in the refcount code where we don't merge
records correctly if the refcount is hovering around MAXREFCOUNT.  This
fixes regressions in xfs/179 when fsdax is enabled.  xfs/179 itself will
be modified to exploit the bug through the pagecache path.
