These two patches fix use-after-free errors in the shutdown path of the lpfc driver with both the Initiator and Target mode usage of FC ports.
The problem is very apparent with slub_debug enabled, as the memory poisoning prevents the wait_for_completion_timeout() from returning after the object has been freed. Ewan D.
