["Paul Goyette" <pgoyette%netbsd.org@localhost>]

Module Name:    src
Committed By:   pgoyette
Date:           Tue Jan 21 20:33:01 UTC 2014

Modified Files:
        src/sys/opencrypto: cryptodev.c

Log Message:
Implement in-module ref-counting, and do not allow auto-unload if there
are existing references.

Note that manual unloading is not prevented.

OK christos@

XXX Also note that there is still a small window where the ref-count can
XXX be decremented, and then the process/thread preempted.  If auto-unload
XXX happens before that thread can return from the module's code, bad
XXX things (tm) could happen.
