Modified files:
sys/scsi : sd.c sdvar.h
Log message:
ask the disk about unmap (read trim) parameters. check if we have the
required vpd pages, then read them for the values we want.
we look for the max blocks per unmap, the max descriptors per unmap, and
which scsi command to use for unmapping (unmap will be preferred).
two fixes and ok matthew@
