Hi all, this is a resend of a small patchset for cleaning up SCSI EH. Primary goal is to make asynchronous aborts mandatory; there hasn't been a single report so far where asynchronous abort won't work, so the 'no_async_abort' flag has never been used and will be removed with this patchset. Additionally there's a cleanup for handle failed EH commands, and to detect retries of failed commands. I've also included the patch to correctly reset the media access timeout counter to avoid it being triggered inadvertedly by several commands timing out for the same device. As usual, comments and reviews are welcome. Changes to v1: - Include reviews from Christoph Changes to v2: - Include reviews from Bart - Add medium access timeout patch Christoph Hellwig (1): libsas: allow async aborts Hannes Reinecke (5): scsi_error: count medium access timeout only once per EH run scsi: make eh_eflags persistent scsi_error: do not escalate failed EH command scsi: make scsi_eh_scmd_add() always succeed scsi: make asynchronous aborts mandatory Documentation/scsi/scsi_eh.txt | 30 +++----- drivers/scsi/libsas/sas_scsi_host.c | 5 -- drivers/scsi/scsi_error.c | 143 +++++++++--------------------------- drivers/scsi/scsi_lib.c | 4 +- drivers/scsi/scsi_priv.h | 3 +- drivers/scsi/sd.c | 21 +++++- drivers/scsi/sd.h | 1 + include/scsi/scsi_driver.h | 2 +- include/scsi/scsi_eh.h | 1 + include/scsi/scsi_host.h | 5 -- 10 files changed, 68 insertions(+), 147 deletions(-) -- 1.8.5.6
