Thanks for the pointer to this patch. I think I started this kernel half way
through the 3.16 merge window. The last non-cherry-picked patch I have is:
commit 6d87c225f5d82d29243dc124f1ffcbb0e14ec358
Merge: 338c09a 22001f6
Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>
Date: Thu Jun 12 23:06:23 2014 -0700
Merge branch 'for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
So I do have the change you pointed out. Nevertheless, I'll reconfirm with the
latest torvalds/master.
Thanks,
Christopher
