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.

How reproducible:


Steps to Reproduce:

Actual results:

Sometimes, an osd crashes.

Expected results:

The objects are either reverted or removed.
