My apologies for the spam. The problem occur only if I try to use your patch together with http://review.whamcloud.com/#/c/16838/42. Di will push a update for his patch. I hope this didn't cause unnecessary work.

[Alex Zhuravlev]

hmm, the patch itself doesn't report this.. I'm gonna try locally.
update: it applies and builds.. I've refreshed it to address Andreas's comments.

Hi Alex: We have a problem documented in LU-5565 pointing to this change. Could please upload a rebased version for http://review.whamcloud.com/#/c/18155/
I tried to build on tip of master (commit bb32a147e35f3339832e41e045de68f304ce18cc), but patches don't merge anymore.
This might help avoid reformatting soaked FS. Many thanks in advance.

Assigning to Alex as there is already a patch in flight.
