[PATCH 0/2] bcache: set dc->writebacking_running properly

[Shenghui Wang <shhuiw@xxxxxxxxxxx>]

Set dc->writebacking_running only after writeback kthread created.
And check value of writeback_running set via sysfs against if writeback
kthread already created or not.


Shenghui Wang (2):
  bcache: do not mark writeback_running until backing dev attached to
    cache_set
  bcache: cannot set writeback_running via sysfs if no writeback kthread
    created
