Patch fixes the issue.

inaddy@iscsixfs:~$ sudo modprobe xfs

inaddy@iscsixfs:~$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sdb /dev/sdb1

inaddy@iscsixfs:~$ sudo mount /dev/sda1 /xfs01

inaddy@iscsixfs:~$ ls /xfs01

Disk is back online after module was reloaded.
(I could have checked slab objects for xfs_log_ticket but I guess this is enough).
