[PATCH 0/9] remove q->prepare_flush_fn hook

[FUJITA Tomonori]

This removes q->prepare_flush_fn. Except for ide and scsi, all the
users just mark flush requests. They can use REQ_FLUSH flag
instead.

SCSI and ide can use q->prep_rq_fn to build flush requests.

This can be applied to the block's for-2.6.36.
