Description

When quotas are enabled, by mounting cephfs using ceph-fuse, as

ceph-fuse --id mount_user -k /etc/ceph/ceph.client.mount_user.keyring -m <MON IP>:6789 --client-quota --fuse_default_permissions=0 --client_acl_type=posix_acl -r /cephfs /coepp/cephfs/

we get the following segfault once we expose the clients to users workload

ceph version 10.2.2 (45107e21c568dd033c2f0a3107dec8f0b0e58374)

 NOTE: a copy of the executable, or `objdump -rdS &lt;executable&gt;` is needed to interpret this.

Will attach the full log obtained with 'debug client = 20' to this ticket.
