Description

It was introduced by https://tracker.ceph.com/issues/54049.

From the options:

462 - name: client_die_on_failed_dentry_invalidate
463   type: bool
464   level: advanced
465   desc: kill the client when no dentry invalidation options are available
466   long_desc: The CephFS client requires a mechanism to invalidate dentries in the
467     caller (e.g. the kernel for ceph-fuse) when capabilities must be recalled. If
468     the client cannot do this then the MDS cache cannot shrink which can cause the                                                                 
469     MDS to fail.
470   default: true
471   services:
472   - mds_client

If we don't abort the client daemons it probably will cause the MDSs to fail.
