[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.
