Modified files:
sys/cam/scsi scsi_sa.c
Log:
Use the residual from a spacing operation to try and figure out where
we *really* are.
It should be noted that there is a degenerate case where soft tape
location will be lost (not causing a frozen state- but causing
the loss of reporting fileno/blockno)- that's where you backspace
over a filemark- you stop backspacing as soon as you cross the
filemark, but you have no idea what the record number now is because
you have no idea how many records you are into the file you just
backed into. Such is life.
While I'm at it, also pick up residuals from writing filemarks.
