Subject: block: merge blk_invoke_request_fn() into __blk_run_queue()
X-Git-Tag: v2.6.31-rc1~389^2~122
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a538cd03be6f363d039daa94199c28cfbd508455;p=pandora-kernel.git

block: merge blk_invoke_request_fn() into __blk_run_queue()

__blk_run_queue wraps blk_invoke_request_fn() such that it
additionally removes plug and bails out early if the queue is empty.
Both extra operations have their own pending mechanisms and don't
cause any harm correctness-wise when they are done superflously.

The only user of blk_invoke_request_fn() being blk_start_queue(),
there isn't much reason to keep both functions around.  Merge
blk_invoke_request_fn() into __blk_run_queue() and make
blk_start_queue() use __blk_run_queue() instead.

[ Impact: merge two subtly different internal functions ]
