211Date: January 2012

213Description:
214 Some devices support a write same operation in which a
215 single data block can be written to a range of several
216 contiguous blocks on storage. This can be used to wipe
217 areas on disk or to initialize drives in a RAID
218 configuration. write_same_max_bytes indicates how many
219 bytes can be written in a single write same command. If
220 write_same_max_bytes is 0, write same is not supported
221 by the device.
