svn commit: r239889 - head/sys/dev/isci/scil

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.
