This commit is causing a flood of connections to Samba server as well
as high server CPU load when the Samba is restarted while CIFS share
is mounted on the client. This can cause the Samba server to become
slow or unresponsive resulting in denial of service to other users
connected to the Samba server.
Bug report: https://bugzilla.kernel.org/show_bug.cgi?id=194531
Could you please have a look?
Thanks.
Regards,
Jonathan
