Hi, This patch series has several small trivial cleanups and few code optimizations. Due to conflicting nature of patches I've generated this series on the top of timeout [1]. Regards, Chaitanya [1] http://lists.infradead.org/pipermail/linux-nvme/2020-November/020797.html Changes from V3:- 1. Simplify nvme_alloc_request() and nvme_alloc_request_qid(). 2. Add helpers which are used by request alloc functions. 3. Rebase and retest the code. 4. Only init bio_end_io for bio_alloc() case in passthru. 5. Add reviewed-by tags. 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.
