[PATCH 12/12] be2iscsi: Add lock to protect WRB alloc and free

2016-02-01 Thread Jitendra Bhivare
FW got into UE after running IO stress test With kernel change to split session lock in frwd_lock and back_lock for tx and rx path correspondingly, in the IO path, common resource used in driver such as WRB was left unprotected. Add wrb_lock spinlock to protect allocation and freeing of WRB. Sig
