Subject: [PATCH 0/6] blk-mq: initialize pdu of flush req explicitly
Date: Sun, 7 Sep 2014 16:39:16 +0800 [thread overview]
Message-ID: <1410079162-9872-1-git-send-email-ming.lei@canonical.com> (raw)
Hi,
This patchset introduces init_flush_rq and its pair callback to
initialize pdu of flush request explicitly, instead of using
copying from request which is inefficient and buggy, and implements
them in virtio-blk and scsi-lib.
block/blk-flush.c | 22 +++++++++++++++++++++-
block/blk-mq.c | 23 ++++++++---------------
block/blk-mq.h | 3 ++-
drivers/block/virtio_blk.c | 15 ++++++++++++++-
drivers/scsi/scsi_lib.c | 32 +++++++++++++++++++++++++++-----
include/linux/blk-mq.h | 9 +++++++++

Thanks,
