Changes by: krwcvs.openbsd.org 2009/07/02 12:50:37
Modified files:
sys/dev/usb : umass_scsi.c
Log message:
Revert the 'optimization' I attempted in r1.21 since it turns out
that returning COMPLETE for non-SCSI_POLL commands is significant.
Fixes double free of xs and subsequent crashes caused by pulling
out USB media while i/o is active. Problem analyzed & fix discovered
by hshoexer. A more general fix may follow post-4.6.
ok miod deraadt.
