Description Venky Shankar 2019-08-22 10:49:52 UTC 
[applies to all components, but keeping it as RBD as the tracker ticket was reported against that]

Description of problem:
Thread unsafe invocations of config observers (for fetching config overrides) results in crashes (as mentioned in the ceph tracker ticket -- python based tools using rbd python api kept crashing).

Version-Release number of selected component (if applicable):
3.3

How reproducible:
easily reproducible


Steps to Reproduce:
ceph tracker ticket has reproducer scripts attached.

Actual results:
App crashes.

Expected results:
no crashes/backtraces, clean init/shutdown and execution of the app.
Comment 3 Jason Dillaman 2019-09-11 14:13:24 UTC 
Bumping to z2 since it's a non-trivial cherry-pick is require for RHCS 3.x.
