Tejun Heo ef9be1d336 [BLOCK] as-iosched: update alias handling
Unlike other ioscheds, as-iosched handles alias by chaing them using
rq->queuelist.  As aliased requests are very rare in the first place,
this complicates merge/dispatch handling without meaningful
performance improvement.  This patch updates as-iosched to dump
aliased requests into dispatch queue as other ioscheds do.

Jens Axboe 8ad9ebb391 [PATCH] as-iosched: remove state assertion in as_add_request()
Kill the arq->state poison statement in as_add_request(), it can trigger
for perfectly valid code that just reuses a request after io completion
instead of freeing it and allocating a new one. We probably should
introduce a blk_init_request() to start from scratch, but for now just
kill it as we will be removing the as specific poisoning soon.

Coywolf Qi Hunt eb97b73d75 [BLOCK] new block/ directory comment tidy
Some leftover comments referring to drivers/block that are now block/.
They don't add any information we don't already have, so kill them.

Jens Axboe 3a65dfe8c0 [BLOCK] Move all core block layer code to new block/ directory
drivers/block/ is right now a mix of core and driver parts. Lets move
the core parts to a new top level directory. Al will move the fs/
related block parts to block/ next.
