Subject: [PATCH 1/2] BZ 2124214 - schema compat plugin deadlock on delete post
op
Bug description:
backends locks (SC map and retroCL) are acquired in
the opposite order
(https://bugzilla.redhat.com/show_bug.cgi?id=2124214#c17)
Fix description:
Credits of the fix are to Pierre Rogier who found
a reproducible testcase, did the fix and verified it.
In specific condition of retroCL trimming the DEL
callback of the SC should check if the backend should
be ignored
