JIRA: https://issues.redhat.com/browse/RHEL-48618 commit 578eb54 Author: Xiubo Li <xiubli@redhat.com> Date: Wed Jul 10 20:16:54 2024 +0800 ceph: periodically flush the cap releases The MDS could be waiting the caps releases infinitely in some corner case and then reporting the caps revoke stuck warning. To fix this we should periodically flush the cap releases.
