181 * READA Used for read-ahead operations. Lower priority,
and the
182 * block layer could (in theory) choose to ignore
this
183 * request if it runs into resource problems.
184 * WRITE A normal async write. Device will be plugged.
185 * WRITE_SYNC Synchronous write. Identical to WRITE, but
passes down
186 * the hint that someone will be waiting on this IO
187 * shortly. The write equivalent of READ_SYNC.
188 * WRITE_ODIRECT Special case write for O_DIRECT only.
189 * WRITE_FLUSH Like WRITE_SYNC but with preceding cache flush.
190 * WRITE_FUA Like WRITE_SYNC but data is guaranteed to be on
191 * non-volatile media on completion.
192 * WRITE_FLUSH_FUA Combination of WRITE_FLUSH and FUA. The IO is
preceded
193 * by a cache flush and data is guaranteed to be on
194 * non-volatile media on completion.
