Subject: KeyValueStore: Fix the prefix comparion to avoid object leaks.
X-Git-Tag: v9.0.2~142^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=9eb760d1d5edba6afa289a6edc6daf05050f80fe;p=ceph.git

KeyValueStore: Fix the prefix comparion to avoid object leaks.

Iterator becomes invalid due to a partial prefix comparision in
rmkeys_by_prefix, resulting in not deleting the objects from backend.
Modified the comparision to the given prefix.
