Title:
  Bitmap allocator returns duplicate entries

Status in ceph package in Ubuntu:
  Fix Released
Status in ceph source package in Bionic:
  Fix Released

Bug description:
  There is a known issue where ceph commit latency can increase over
  time [0], and the "fix" is to move to the new Nautilus bitmap
  allocator back-ported in 12.2.12 [1].

  It has been brought to my attention that one encountered a bug with
  the nautilus bitmap allocator [2] that brought down their cluster.
  This was due to a double-extent allocation which has been fixed and
  back-ported to Luminous, but is targeted for 12.2.13.

  Would be good to add it into our Ubuntu ceph package(s) where it
  applies to get ahead of the op commit latency problem.

  The bug is reported upstream and being discussed here [3] [4].
