Subject: [PATCH 0/2] ceph: Properly clean up after failures in ceph_submit_write()

Hi list,

This series contains two patches from my previous series [1] that are
independent and have no outstanding review comments.

The patches fix a crash that can occur if ceph_inc_osd_stopping_blocker()
fails on write, and split out the complex page-array cleanup logic to a new
helper function (per Slava's suggestion). The first patch is intended for
stable.

There is no known reproducer for this race condition; it appears to be
timing-sensitive. I have a fault-injection patch that can trigger it, which I
can provide on request.

Warm regards,
Sam
