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