The following patches begin to cleanup the request->cmd_flags and bio->bi_rw mess. We currently use cmd_flags to specify the operation, attributes and state of the request. For bi_rw we use it for similar info and also the priority but then also have another bi_flags field for state. At some

[PATCH 07/42] btrfs: have submit_one_bio users setup bio bi_op

From: Mike Christie This patch has btrfs's submit_one_bio callers set the bio->bi_op to a REQ_OP and the bi_rw to rq_flag_bits. The next patches will continue to convert btrfs, so submit_bio_hook and merge_bio_hook related code will be modified to take only the bio. I did not do it in this

[PATCH 02/42] block: add REQ_OP definitions and bi_op/op fields

From: Mike Christie The following patches separate the operation (write, read, discard, etc) from the rq_flag_bits flags. This patch adds definitions for request/bio operations, adds fields to the request/bio to set them, and some temporary compat code so the kernel/modules can use either one.

[PATCH 08/42] btrfs: set bi_op tp REQ_OP

From: Mike Christie This patch has btrfs use the bio bi_op for REQ_OP and bi_rw for rq_flag_bits. v5: - Misset bi_rw to REQ_OP_WRITE in finish_parity_scrub Signed-off-by: Mike Christie Reviewed-by: Christoph Hellwig Reviewed-by: Hannes Reinecke --- fs/btrfs/check-integrity.c | 19

[PATCH 03/42] block, fs, mm, drivers: set bi_op to REQ_OP

From: Mike Christie This patch converts the simple bi_rw use cases in the block, drivers, mm and fs code to set the bio->bi_op to a REQ_OP. These should be simple one liner cases, so I just did them in one patch. The next patches handle the more complicated cases in a

[PATCH 06/42] direct-io: set bi_op to REQ_OP

From: Mike Christie This patch has the dio code set the bio bi_op to a REQ_OP and bio op_flags to rq_flag_bits. It also begins to convert btrfs's dio_submit_t because of the dio submit_io callout use. In the btrfs_submit_direct change, I OR'd the op and flag back together.
