Subject: [RFC PATCH v2 0/2] dm: dm_blk_ioctl(): implement failover for SG_IO on dm-multipath
Date: Thu, 29 Apr 2021 17:50:22 +0200	[thread overview]
Message-ID: <20210429155024.4947-1-mwilck@suse.com> (raw)

From: Martin Wilck <mwilck@suse.com>

Hi Mike,

here is v2 of my attempt to add retry logic to SG_IO on dm-multipath devices.

Regards
Martin

Changes v1->v2:

 - applied modifications from Mike Snitzer
 - moved SG_IO dependent code to a separate file, no scsi includes in
   dm.c any more
 - made the new code depend on a configuration option 
 - separated out scsi changes, made scsi_result_to_blk_status()
   inline to avoid dependency of dm_mod from scsi_mod (Paolo Bonzini)

Martin Wilck (2):
  scsi: convert scsi_result_to_blk_status() to inline
  dm: add CONFIG_DM_MULTIPATH_SG_IO - failover for SG_IO on dm-multipath
