[PATCH-v1 14/22] Remove hba lock from NVMET issue WQE.

2017-04-19 Thread jsmart2021
From: James Smart Unnecessary lock is taken. ring lock should be sufficient to protect the work queue submission. This was noticed when doing performance testing. The hbalock is not needed to issue io to the nvme work queue. Signed-off-by: Dick Kennedy
