Hi Kent, all!
Yesterday I was testing bcacefs mounted at /home on desktop. Next I
hibernated box. Today I resumed OS, upgraded kernel to:
commit ee9f55a7cd209a821f79c1092b5c53959ab1bc47

bcache: don't flush journal unnecessarily
commit 125312566ed797bc0c8b87ae9dbf694a68ddef33
Author: Kent Overstreet <kent.overstreet@xxxxxxxxx>
Date: Mon Dec 12 12:53:56 2016 -0900
bcache: short circuit bch_prio_write() and journal flush when possible
and next I rebooted. Now I can't mount /home because of error (it's not
problem, I've got backup). Error is:
