From ad689233bee854dced741c91aff12a8771a22f6f Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Fri, 26 Jan 2007 14:08:52 -0800 Subject: [SCSI] libsas: Handle SCSI commands that complete with failure codes This patch moves the code that handles SAS failures out of the main EH function and into a separate function. It also detects commands that have no sas_task (i.e. they completed, but with error data) and sends them into scsi_error for processing. This allows us to handle SCSI errors (and enables auto-spinup as a side effect) instead of dropping them on the floor and falling into an infinite loop. It also requires the implementation of a device reset function, which the SAS failure code has been modified to employ for REQ_DEVICE_RESET. Signed-off-by: Darrick J.
