From: Martin Wilck <mwilck@xxxxxxxx> 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 block/scsi_ioctl.c | 5 +- drivers/md/Kconfig | 11 ++++ drivers/md/Makefile | 4 ++ drivers/md/dm-core.h | 5 ++ drivers/md/dm-rq.h | 11 ++++ drivers/md/dm-scsi_ioctl.c | 127 +++++++++++++++++++++++++++++++++++++ drivers/md/dm.c | 20 +++++- drivers/scsi/scsi_lib.c | 40 ------------ include/linux/blkdev.h | 2 + include/scsi/scsi_cmnd.h | 83 ++++++++++++++++++++++-- 10 files changed, 259 insertions(+), 49 deletions(-) create mode 100644 drivers/md/dm-scsi_ioctl.c -- 2.31.1 -- dm-devel mailing list dm-devel@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/dm-devel
