[PATCHv2 0/5] SCSI EH cleanup

[Hannes Reinecke <hare@suse.de>]

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.

As usual, comments and reviews are welcome.

Changes to v1:
- Include reviews from Christoph

Christoph Hellwig (1):
  libsas: allow async aborts

Hannes Reinecke (4):
  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
