block: continue ll_rw_blk.c splitup Adds files for barrier handling, rq execution, io context handling, mapping data to requests, and queue settings. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

Add some block/ source files to the kernel-api docbook. Fix kernel-doc notation in them as needed. Fix changed function parameter names. Fix typos/spellos. In comments, change REQ_SPECIAL to REQ_TYPE_SPECIAL and REQ_BLOCK_PC to REQ_TYPE_BLOCK_PC. Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

block: unexport blk_end_sync_rq All the users of blk_end_sync_rq has gone (they are converted to use blk_execute_rq). This unexports blk_end_sync_rq.

block: remove per-queue plugging Code has been converted over to the new explicit on-stack plugging, and delay users have been converted to use the new API for that. So lets kill off the old plugging along with aops->sync_page(). Signed-off-by: Jens Axboe <jaxboe@fusionio.com>

block: add blk_run_queue_async Instead of overloading __blk_run_queue to force an offload to kblockd add a new blk_run_queue_async helper to do it explicitly. I've kept the blk_queue_stopped check for now, but I suspect it's not needed as the check we do when the workqueue items runs should be enough.

block: Remove 'plug/unplug' comment in blk_execute_rq_nowait unplug is replaced with blk_run_queue now in blk_execute_rq_nowait, so change the comment accordingly. Signed-off-by: Tao Ma <boyu.mt@taobao.com> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>

block: remove wrappers for request type/flags Remove all the trivial wrappers for the cmd_type and cmd_flags fields in struct requests. This allows much easier grepping for different request types instead of unwinding through macros. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>

block: handle blk_pm_resume_request() requests in blk_execute_rq_nowait() For blk_pm_resume_request() requests (which are used only by IDE subsystem currently) the queue is stopped so we need to call ->request_fn explicitly. Thanks to: - Rafael for reporting/bisecting the bug - Borislav/Rafael for testing the fix This is a preparation for converting IDE to use blk_execute_rq().

block: Prevent hang_check firing during long I/O During long I/O operations, the hang_check timer may fire, trigger stack dumps that unnecessarily alarm the user. Eg. hdparm --security-erase NULL /dev/sdb ## can take *hours* to complete So, if hang_check is armed, we should wake up periodically to prevent it from triggering. This patch uses a wake-up interval equal to half the hang_check timer period, which keeps overhead low enough.
