| Message-ID | <ro9Nn-21n-1@gated-at.bofh.it> |
| In reply to | #1379693 |
From: Mike Christie <mchristi@redhat.com>
This patch has drbd use bio->bi_op for REQ_OPs and rq_flag_bits
to bio->bi_rw.
Lars and Philip, I might have split this patch up a little weird.
The block layer has compat so you can set either bi_rw or bi_op.
This patch handles setting up the bio in drbd. I then converted
all the block device drivers and in
0037-block-fs-drivers-do-not-test-bi_rw-for-REQ_OPs.patch I modified
the bi_rw checks so they use bi_op.
This patch is compile tested only.

| Message-ID | <ro9No-21n-9@gated-at.bofh.it> |
| In reply to | #1379693 |
From: Mike Christie <mchristi@redhat.com>
This patch prepares *_get_request/*_put_request and freed_request,
to use separate variables for the operation and flags. In the
next patches the struct request users will be converted like
was done for bios. request->op will be used for the REQ_OP and
request->cmd_flags for the rq_flag_bits.
There is some temporary compat code in __get_request to
allow users to read the operation from the cmd_flags. This will
be deleted in one of the last patches when all drivers have
been converted.

This patch modifies the blk mq request creation code to use
separate variables for the operation and flags, because in the
the next patches the struct request users will be converted like
was done for bios. request->op will be used for the REQ_OP and
request->cmd_flags for the rq_flag_bits.
Like the non mq patch there is some temporary compat code in
blk_mq_rq_ctx_init to allow users to read the operation from the
cmd_flags. This will be deleted in one of the last patches when all
drivers have been converted.

From: Mike Christie <mchristi@redhat.com>
It looks like dm stats cares about the data direction
(READ vs WRITE) and does not need the bio/request flags.
Commands like REQ_FLUSH, REQ_DISCARD and REQ_WRITE_SAME
are currently always set with REQ_WRITE, so the extra check for
REQ_DISCARD in dm_stats_account_io is not needed.
This patch has it use the bio and request data_dir helpers
instead of accessing the bi_rw/cmd_flags directly. This makes
the next patches that remove the operation from the cmd_flags
and bi_rw easier, because we will no longer have the REQ_WRITE
bit set for operations like discards.
This patch is compile tested only.
v2:
1. Merged Mike Snitzer's fixes to pass in int instead of
unsigned long.
2. Fix 80 char col issues.

From: Mike Christie <mchristi@redhat.com>
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. It is only temporary. The next patched will completely convert
all the btrfs code paths.

| Subject | [PATCH 07/42] btrfs: have submit_one_bio users setup bio bi_op |
| Message-ID | <ro9X4-25i-23@gated-at.bofh.it> |
| In reply to | #1379693 |
From: Mike Christie <mchristi@redhat.com>
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 to try and keep it smaller.

From: Mike Christie <mchristi@redhat.com>
We no longer pass in a bitmap of rq_flag_bits bits to __btrfs_map_block.
It will always be a REQ_OP, or the btrfs specific REQ_GET_READ_MIRRORS,
so this drops the bit tests.

| Subject | [PATCH 03/42] block, fs, mm, drivers: set bi_op to REQ_OP |
| Message-ID | <ro9X5-25i-47@gated-at.bofh.it> |
| In reply to | #1379693 |
From: Mike Christie <mchristi@redhat.com>
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 module per patch.
v5:
1. Add missed crypto call.
2. Change nfs bi_rw check to bi_op.
