X-Git-Tag: v2.6.25-rc1~1172^2~9
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5e36bb6ee8d5ff6c6114b60d2aaa1c70d4275f4e;p=pandora-kernel.git

blk_end_request: changing ide normal caller (take 4)

This patch converts "normal" parts of ide to use blk_end_request
interfaces.  Related 'uptodate' arguments are converted to 'error'.

The conversion of 'uptodate' to 'error' is done only for the internal
function, __ide_end_request().
ide_end_request() was not changed since it's exported and used
by many ide drivers.

With this patch, blkdev_dequeue_request() in __ide_end_request() is
moved to blk_end_request, since blk_end_request takes care of
dequeueing request like below:

	if (!list_empty(&rq->queuelist))
		blkdev_dequeue_request(rq);

In the case of ide,
  o 'dequeue' variable of __ide_end_request() is 1 only when the request
    is still linked to the queue (i.e. rq->queuelist is not empty)
  o 'dequeue' variable of __ide_end_request() is 0 only when the request
    has already been removed from the queue (i.e. rq->queuelist is empty)
So blk_end_request can handle it correctly although ide always run
thought the code above.
