New Revision: 239889
URL: http://svn.freebsd.org/changeset/base/239889
Log:
Do not call sati_check_data_io() for SATI_UNMAP sequences.
This routine is intended only for commands such as INQUIRY where
the controller may fill out a smaller amount of data than allocated
by the host.
The end result of this bug was that isci(4) would report non-zero
resid for successful SCSI_UNMAP commands.
