Merge branch '3.4-rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull target fixes from Nicholas Bellinger:
"Pull two tcm_fc fabric related fixes for -rc2:
Note that both have been CC'ed to stable, and patch #1 is the
important one that addresses a memory corruption bug related to FC
exchange timeouts + command abort.
Thanks again to MDR for tracking down this issue!"
* '3.4-rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
tcm_fc: Do not free tpg structure during wq allocation failure
tcm_fc: Add abort flag for gracefully handling exchange timeout
