As SCSI SBC4 specification section 5.30.2 describes that it can

However, previously we only pack one LBA range in UNMAP command by
default no matter device gives the block limits that says it can
support unmapping multiple LBA ranges with a single UNMAP command.
This patch sets max_discard_segments config according to block limits
of device, and supports unmapping multiple LBA ranges with a single
UNMAP command.
This looks OK to me. Will test with a variety of targets.
Hi Martin,
Have you already had the chance to test this patch? We would like to use
this functionality in Android.
Thanks,
Bart.
