[PATCH 33/35] block, drivers: add REQ_OP_FLUSH operation

From: Mike Christie This adds a REQ_OP_FLUSH operation that is sent to request_fn based drivers by the block layer's flush code, instead of sending requests with the request->cmd_flags REQ_FLUSH bit set. For the following 3 flush related patches, I have not tested every driver. I have only teste

[PATCH 03/35] 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 use bi_op for a REQ_OP and bi_rw for rq_flag_bits. 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 p

[PATCH 34/35] block: add QUEUE_FLAGs for flush and fua

From: Mike Christie The last patch added a REQ_OP_FLUSH for request_fn drivers and the next patch renames REQ_FLUSH to REQ_PREFLUSH which will be used by file systems and make_request_fn drivers. This leaves REQ_FLUSH/REQ_FUA defined for drivers to tell the block layer if flush/fua is supported.

[PATCH 20/35] dm: pass dm stats data dir instead of bi_rw

From: Mike Christie 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 need
