From 66a651aa7a48b7c6181aff556937454c87bb9feb Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Mon, 13 Feb 2012 15:38:22 -0500 Subject: [PATCH] [SCSI] Ensure discard failure gets treated as a target problem The error reported up the stack for a discard failure did not clearly indicate that the command was processed and subsequently failed by the target device. Return -EREMOTEIO so multipathing does not classify this condition as a path failure. Signed-off-by: Martin K.
