Doc Text:
.OSDs no longer crash when running `mark_lost_revert` or `mark_lost_delete` Previously, issuing the `mark_lost_revert` and `mark_lost_delete` commands during active client write operations could cause the OSD daemons to terminate unexpectedly. The underlying code has been modified, and OSDs no longer crash in the described scenario.

Description Samuel Just 2016-02-05 20:09:11 UTC

How reproducible:

Steps to Reproduce:
1. Produce unfound objects (see the ceph-qa-suite tests which do this)
2. Run client writes (like rados bench)
3. Run mark_unfound_[delete|revert]

Actual results:

Sometimes, an osd crashes.

Expected results:

The objects are either reverted or removed.
