[PATCH] dm crypt: move io to workqueue
This patch is designed to help dm-crypt comply with the
new constraints imposed by the following patch in -mm:
md-dm-reduce-stack-usage-with-stacked-block-devices.patch
Under low memory the existing implementation relies upon waiting for I/O
submitted recursively to generic_make_request() completing before the original
generic_make_request() call can return.
This patch moves the I/O submission to a workqueue so the original
generic_make_request() can return immediately.
