Subject[PATCHSET block:for-3.2/core] further updates to blk_cleanup_queue()
Date
Hello,

Patchset "fix request_queue life-cycle management"[1] tried to fix
lifecycle management by making blk_cleanup_queue() drain and shut down
the queue; however, there still are some holes. This patchset
tightens externally visible API a bit and plugs those holes.

0001-block-sx8-kill-blk_insert_request.patch
0002-block-allow-blk_execute_rq_nowait-to-be-called-form-.patch
0003-block-ide-unexport-elv_add_request.patch
0004-block-add-blk_queue_dead.patch
0005-block-fix-drain_all-condition-in-blk_drain_queue.patch
0006-block-add-missing-blk_queue_dead-checks.patch

0001-0003 remove/unexport two request insertion functions which don't
have proper DEAD check. Users are switched to
blk_execute_rq_nowait().

0004 adds blk_queue_dead() macro for convenience.

0005 updates blk_drain_queue() such that it also waits for requests
which weren't allocated from block layer.

0006 adds missing DEAD checks.

This patchset is on top of the block:for-3.2/core 3bcfeaf93f4 "block:
initialize the bounce pool if high memory may be added later" and
available in the following git branch.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git block-ref
