/*
 * The below are the various read and write types that we support. Some of
 * them include behavioral modifiers that send information down to the
 * block layer and IO scheduler. Terminology:
 *
 *	The block layer uses device plugging to defer IO a little bit, in
 *	the hope that we will see more IO very shortly. This increases
 *	coalescing of adjacent IO and thus reduces the number of IOs we
 *	have to send to the device. It also allows for better queuing,
 *	if the IO isn't mergeable. If the caller is going to be waiting
 *	for the IO, then he must ensure that the device is unplugged so
 *	that the IO is dispatched to the driver.
 *
 *	All IO is handled async in Linux. This is fine for background
 *	writes, but for reads or writes that someone waits for completion
 *	on, we want to notify the block layer and IO scheduler so that they
 *	know about it. That allows them to make better scheduling
 *	decisions. So when the below references 'sync' and 'async', it
 *	is referencing this priority hint.
 *
 * With that in mind, the available types are:
 *
 * READ			A normal read operation. Device will be plugged.
 * READ_SYNC		A synchronous read. Device is not plugged, caller can
 *			immediately wait on this read without caring about
 *			unplugging.
 * READA		Used for read-ahead operations. Lower priority, and the
 *			 block layer could (in theory) choose to ignore this
 *			request if it runs into resource problems.
 * WRITE		A normal async write. Device will be plugged.
 * SWRITE		DEPRECATED; use write_dirty_buffer instead.
 *			Like WRITE, but a special case for ll_rw_block() that
 *			tells it to lock the buffer first. Normally a buffer
 *			must be locked before doing IO.
 * WRITE_SYNC_PLUG	Synchronous write. Identical to WRITE, but passes down
 *			the hint that someone will be waiting on this IO
 *			shortly. The device must still be unplugged explicitly,
 *			WRITE_SYNC_PLUG does not do this as we could be
 *			submitting more writes before we actually wait on any
 *			of them.
 * WRITE_SYNC		Like WRITE_SYNC_PLUG, but also unplugs the device
 *			immediately after submission. The write equivalent
 *			of READ_SYNC.
 * WRITE_ODIRECT_PLUG	Special case write for O_DIRECT only.
 * SWRITE_SYNC
 * SWRITE_SYNC_PLUG	DEPRECATED. Like WRITE_SYNC/WRITE_SYNC_PLUG, but locks
 *			the buffer. See SWRITE.
 * WRITE_BARRIER	DEPRECATED. Always fails. Use FLUSH/FUA instead.
 * WRITE_FLUSH		Like WRITE_SYNC but with preceding cache flush.
 * WRITE_FUA		Like WRITE_SYNC but data is guaranteed to be on
 *			non-volatile media on completion.
 * WRITE_FLUSH_FUA	Combination of WRITE_FLUSH and FUA. The IO is preceded
 *			by a cache flush and data is guaranteed to be on
 *			non-volatile media on completion.
