Subject: [PATCH V3 0/6] nvmet: passthru fixes and improvements
Date: Wed, 21 Oct 2020 18:02:28 -0700
Message-ID: <20201022010234.8304-1-chaitanya.kulkarni@wdc.com> (raw)

Hi,

This patch series has several small trivial fixes and few code
optimizations.

Regards,
Chaitanya

Changes from V2:-

1. Remove "nvme-core: annotate nvme_alloc_request()" patch and
   split the nvme_alloc_request() into nvme_alloc_request_qid_any()
   and nvme_alloc_request_qid() with addition of the prep patch for
   the same.
2. Remove the cleanup patches and trim down the series.
3. Remove the code for setting up the op_flags for passthru.  
4. Rebase and retest on the nvme-5.10.

Changes from V1:-

1. Remove the sg_cnt check and nvmet_passthru_sg_map() annotation.
2. Add annotations and performance numbers for newly added patch #1.
3. Move ctrl refcount and module refcount into nvme_dev_open() and
   nvme_dev_release(). Add prepration patch for the same.
4. Add reviewed-by tags.

Chaitanya Kulkarni (6):
  nvme-core: add a helper to init req from nvme cmd
  nvme-core: split nvme_alloc_request()
  nvmet: remove op_flags for passthru commands
  block: move blk_rq_bio_prep() to linux/blk-mq.h
  nvmet: use minimized version of blk_rq_append_bio
  nvmet: use inline bio for passthru fast path
