Cifs mounts get unmonted sporadically

SUSE Linux Enterprise Server 12
Cifs mounts can be mounted manually after they are unmounted and get remounted successfully during reboot.
Running df -h hangs or takes a long time to come back if at all. Ctrl-C of the df -h command and running a
grep -i cifs /proc/mounts | wc -l
show that the count of the cifs mounts is lower than what should be mounted.
The SLES12 SP3 kernel maintenance update, kernel-default-4.4.180-94.138.1 released in February 2021 includes the patch to resolve the problem. Updates for other SLES/SP versions will follow.
For the nested mount the VFS layer is put()-ing the dentry of the nested point which triggers the umount().
