Bug Description
[Impact]
In RGW deployments with large deltas for deleted objects, the garbage collector will easily fall behind on cleanup of deleted objects eventually resulting in OSD devices hitting storage capacity.
[Test Case]
Deploy Ceph + RADOS Gateway
Create millions of objects in an iterative loop
Start deleting objects in parallel at a high rate
Storage capacity will gradually reduce over time as RGW garbage collection falls behind.
[Tricky to reproduce without significant scale of objects + deletion but proposed fix has been tested in the field.]
[Regression Potential]
Low - fix has been accepted into Ceph Luminous upstream and will form part of the next point release. Change to use AIO for GC is also in later Ceph releases.
[Original Bug Report]
SRU for backport of the GC AIO feature to Ceph Luminous.

This will be part of 12.2.13 - what's the urgency around this SRU?
We can cherry pick the fix OR wait for the point release.
