From 6e883b0e42739aa560133cfaf41be1138c51a500 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Thu, 17 Sep 2009 17:00:26 +0200 Subject: [SCSI] Retry ADD_TO_MLQUEUE return value for EH commands A target reset when I/O is ongoing might result an eventual device offline, as scsi_eh_completed_normally() might return ADD_TO_MLQUEUE in addition to the advertised SUCCESS, FAILED, and NEEDS_RETRY. Which is unfortunate as scsi_send_eh_cmnd() will therefore map ADD_TO_MLQUEUE to FAILED instead of the more appropriate NEEDS_RETRY.
