Hello all,
This patchset attempts to address problems we've been having with
panics due to memory corruption from the mpt2sas driver.
Thanks,
Calvin
Patches in this series:
[PATCH 1/2] mpt2sas: Refcount sas_device objects and fix unsafe list usage
[PATCH 2/2] mpt2sas: Refcount fw_events and fix unsafe list usage
Changes since v1:
* Squished patches 1-3 and 4-6 into two patches
* s/BUG_ON(!spin_is_locked/assert_spin_locked/g
* Use more succinct fuction names
* Store a pointer to the sas_device object in ->hostdata to eliminate
the need for several lookups on the lists.
* Remove the fw_event from fw_event_list at the start of
_firmware_event_work()
* Explicitly separate fw_event_list removal from fw_event freeing
