[PATCH 0/2] Fix a race condition when performing a controller reset

[Maurizio Lombardi]

Memory leaks and kernel panics involving the nvmet driver
have been observed when an initiator executes a reset_controller
operation while doing I/O.

The problem is due to a race condition between io_work
and release_queue, the latter may end up destroying the
commands while io_work is still running, causing use-after-free
and memory leaks.

Maurizio Lombardi (2):
  nvmet: add an helper to free the iovec
  nvmet: fix a race condition between release_queue and io_work
