Subject: be2iscsi : Fix kernel panic during reboot/shutdown
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=53281edb2942c4d7abf12846b6b0591caf2bee4d;p=linux-beck.git

be2iscsi : Fix kernel panic during reboot/shutdown

 In the reboot/shutdown path, workqueue was destroyed after the
 adapter resource were freed. The task associated with workqueue
 was getting executed after resources were freed. This lead to
 kernel panic.
