From 256bd4f23d9cecaba2e6795f0058fa9c2362698c Mon Sep 17 00:00:00 2001 From: Sreekanth Reddy Date: Fri, 6 May 2022 00:18:06 +0530 Subject: [PATCH] scsi: mpi3mr: Return I/Os to an unrecoverable HBA with DID_ERROR Complete all new I/O requests issued to an unrecoverable controller with DID_ERROR status instead of returning the I/O requests with SCSI_MLQUEUE_HOST_BUSY. This will prevent the infinite retries of the new I/Os when a controller is in an unrecoverable state.
