  • 14d87e6c3   sparc: Fix cleanup crash in bbc_envctrl_cleanup() ... Browse Code »

    If kthread_run() fails or never gets to run we'll have NULL
    or a pointer encoded error in kenvctrld_task, rather than
    a legitimate task pointer.

    So this makes bbc_envctrl_cleanup() crash as it passed this
    bogus pointer into kthread_stop().

  • 9934c8c04   block: implement and enforce request peek/start/fetch ... Browse Code »

    Till now block layer allowed two separate modes of request execution.
    A request is always acquired from the request queue via
    elv_next_request(). After that, drivers are free to either dequeue it
    or process it without dequeueing. Dequeue allows elv_next_request()
    to return the next request so that multiple requests can be in flight.

    Executing requests without dequeueing has its merits mostly in
    allowing drivers for simpler devices which can't do sg to deal with
    segments only without considering request boundary. However, the
    benefit this brings is dubious and declining while the cost of the API
    ambiguity is increasing. Segment based drivers are usually for very
    old or limited devices and as converting to dequeueing model isn't
    difficult, it doesn't justify the API overhead it puts on block layer
    and its more modern users.

    Previous patches converted all block low level drivers to dequeueing
    model. This patch completes the API transition by...

    * renaming elv_next_request() to blk_peek_request()

    * renaming blkdev_dequeue_request() to blk_start_request()

    * adding blk_fetch_request() which is combination of peek and start

    * disallowing completion of queued (not started) requests

    * applying new API to all LLDs

    Renamings are for consistency and to break out of tree code so that
    it's apparent that out of tree drivers need updating.

    [ Impact: block request issue API cleanup, no functional change ]

    jsflash processes requests one-by-one synchronously from a kthread and
    can be easily converted to dequeueing model. Convert it.

  • 1011c1b9f   block: blk_rq_[cur_]_{sectors|bytes}() usage cleanup ... Browse Code »

    With the previous changes, the followings are now guaranteed for all
    requests in any valid state.

    * blk_rq_sectors() == blk_rq_bytes() >> 9
    * blk_rq_cur_sectors() == blk_rq_cur_bytes() >> 9

    Clean up accessor usages. Notable changes are

    * nbd,i2o_block: end_all used instead of explicit byte count
    * scsi_lib: unnecessary conditional on request type removed

  • 83096ebf1   block: convert to pos and nr_sectors accessors ... Browse Code »

    With recent cleanups, there is no place where low level driver
    directly manipulates request fields. This means that the 'hard'
    request fields always equal the !hard fields. Convert all
    rq->sectors, nr_sectors and current_nr_sectors references to
    accessors.

    While at it, drop superflous blk_rq_pos() < 0 test in swim.c.

  • f06d9a2b5   block: replace end_request() with [__]blk_end_request_cur() ... Browse Code »

    end_request() has been kept around for backward compatibility;
    however, it's about time for it to go away.

    * There aren't too many users left.

    * Its use of @updtodate is pretty confusing.

    * In some cases, newer code ends up using mixture of end_request() and
    [__]blk_end_request[_all](), which is way too confusing.

    So, add [__]blk_end_request_cur() and replace end_request() with it.
    Most conversions are straightforward. Noteworthy ones are...

    * paride/pcd: next_request() updated to take 0/-errno instead of 1/0.

    * paride/pf: pf_end_request() and next_request() updated to take
    0/-errno instead of 1/0.

    * xd: xd_readwrite() updated to return 0/-errno instead of 1/0.

    * mtd/mtd_blkdevs: blktrans_discard_request() updated to return
    0/-errno instead of 1/0. Unnecessary local variable res
    initialization removed from mtd_blktrans_thread().
