Modified files:
sys/cam cam_ccb.h cam_periph.c
sys/cam/scsi scsi_target.c
Log:
Make physical buffers in cam_periph_mapmem owned by the kernel in case we
return to user space w/o waiting for I/O to complete.
I tried to get several folks who know this code better than me to review it
with no luck. I *do* know that w/o this code, using the SCSI target driver
panics in userret (if it doesn't panic in knote first).
