Module Name:    src
Committed By:   pooka
Date:           Tue Sep  8 21:14:33 UTC 2009

Modified Files:
        src/sys/dev/dkwedge: dk.c

Log Message:
dkwedge_list() is currently called only from ioctl routines where
l == curlwp.  Since there is no perceived case where we'd ever want
to copy the list to non-curlwp, simplify the code a bit.
(the struct lwp * argument could probably be dropped too, but
that's another commit)
