Oops, forgot to mention this is based on the for-next tree with Christoph's xlog-ticket-cleanup.2 branch merged on top. You can pull it from here: git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs.git xfs-fixes-cleanups-5.7 or browse: https://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs.git/log/?h=xfs-fixes-cleanups-5.7 Cheers, Dave. -- Dave Chinner david@xxxxxxxxxxxxx
