I can help that when I merge it this week.
BTW, I saw the "[PATCH 00/15] xfs: Log Attribute Replay" patchset has been
merged by mainline linux. So I suspose it's time to merge this patch. Please
tell me if it's still not the time. As I know there's not only one patchset
is related with this.
And I'll really appreciate that, if any of you would like to list all related
patchset titles (from kernel and userspace) to help this case test pass :)
