+/*
+ * 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               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        Special case write for O_DIRECT only.
+ * SWRITE_SYNC
+ * SWRITE_SYNC_PLUG     Like WRITE_SYNC/WRITE_SYNC_PLUG, but locks the buffer.
+ *                      See SWRITE.
+ * WRITE_BARRIER        Like WRITE, but tells the block layer that all
+ *                      previously submitted writes must be safely on storage
+ *                      before this one is started. Also guarantees that when
+ *                      this write is complete, it itself is also safely on
+ *                      storage. Prevents reordering of writes on both sides
+ *                      of this IO.
