Hi folks, The for-next branch of the xfs-linux repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git has just been updated. Patches often get missed, so please check if your outstanding patches were in this update. If they have not been in this update, please resubmit them to linux-xfs@xxxxxxxxxxxxxxx so they can be picked up in the next update. As promised, this push includes the data corruption fixes for fsdax and reflink mode that Ruan has been working on for some time. I think I'll hold off on pushing this to Linus until the second week of the merge window, because this is a lot of changes to core code (insofar as fs/dax.c is core code) that appeared /very/ late in the 6.2 cycle. I am therefore very tempted to hold it for 6.3, but for the patchset eliminating data corruption vectors. The general lack of users of dax+reflink makes me less anxious about pushing for 6.2, or so I gather since this has been broken since 6.0-rc1 and nobody outside of the fsdevel community has noticed. Thoughts? The new head of the for-next branch is commit: 4883f57a2d86 xfs: remove restrictions for fsdax and reflink 69 new commits: Darrick J.
