From eef76f16295d34d7fab6994b82dda60ce002f91d Mon Sep 17 00:00:00 2001 From: Raghava Aditya Renukunta Date: Mon, 25 Apr 2016 23:32:26 -0700 Subject: [PATCH] aacraid: Remove code to needlessly complete fib Currently driver completes double completed or spurious interrupted fibs. This is not necessary and causes the SCSI mid layer to issue aborts and resets, since completing a fib prematurely might trigger a race condition resulting in the driver not calling the scsi_done callback. Fixed by removing the call to fib complete. Signed-off-by: Raghava Aditya Renukunta Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K.
