From 13c599069130e5a1f04a9409d65566e149b12708 Mon Sep 17 00:00:00 2001 From: Xiang Chen Date: Fri, 20 Jan 2017 20:45:24 +0800 Subject: [PATCH] scsi: hisi_sas: decrease running_req in hisi_sas_slot_task_free() There is an issue that hisi_sas_dev.running_req is not decremented properly for internal abort and TMF. To resolve, only decrease running_req in hisi_sas_slot_task_free() Signed-off-by: Xiang Chen Signed-off-by: John Garry Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K.
