New Revision: 329441
URL: https://svnweb.freebsd.org/changeset/base/329441
Log:
If we're passed an argument, then treat it as a single NOMATCH event
to parse rather than searching for all events. Pass with new -p arg to
devmatch. devmatch will use that one event rather than walking the
entire tree.
kldload will stop at the first failure. So we need to loop. Also,
symbolic links may confused kldload into trying (and failing) to load
multiple modules at once, so guard against that.
