Hi all, This quick 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. If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. Enjoy! Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=maxrefcount-fixes-6.2 --- fs/xfs/libxfs/xfs_refcount.c | 143 +++++++++++++++++++++++++++++++++++++----- 1 file changed, 127 insertions(+), 16 deletions(-)
