[-- Attachment #1 --] Hi Pawel, * Pawel Jakub Dawidek <pjd@FreeBSD.org>, 20111223 12:28: > You changing here vendor code and we still don't want to do that if > avoidable, as we want to share code with IllumOS. To clarify, the changes made to rrwlock.* are likely applicable to IllumOS as well. It effectively fixes misuse of the API, where refcount_t is dereferenced, but also optimizes the code not to use atomics on the counters, as they are already protected by a mutex. -- Ed Schouten <ed@80386.nl> WWW: http://80386.nl/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iQIcBAEBAgAGBQJO9HH1AAoJEG5e2P40kaK7/qoQAKJm/TOW1NFWBqlY9mozcgdU 9VeIHNNr8iqeE7I9XZDu/UiXWzTXyLk0P3FdvpHAIHlwwf7dogiAwu/1fsnltcX6 0pe6tdQpA1sKWuKcCqdTJjT7OTvcP23n2VYv4JFah/FBirh7TdbLEVCqs0VAospr Amw8VLdK7RMMToer71OwI0zDo9jdXvttXOZz9XxIvRtHw1G9tTKUIzJejf0y8wjh zaG8pMW7uqROOIkNRMjA1fxue0uJfjQP4Fg7w/q6MYX44sVyOdgKf6jLin11zTVx 5H7QLapxSl9GUpraZMsu1zMZxQWRmfDDEhLX8Bna/EIlzBROV+BTkmzQCOvHs4zN wRr0uOY+zc/6BHm25jtHqOUKrGQQWdcDKeksxFqlVvntheaVXtW7NcUArVItmUCM hLq0Qz5+ysw7sH/BSRFZmNJLjfCg90UDmYXdBjrPDnZdRB+VdY/ybOtXw612nzC1 jP2b8fI14Xk+pASS9zejulZKYikhLjZQjXbN1N/jsUGTknClWnjMwESN9+sStXFU ZMDheXooaSU+nHMxD6H/PsemfupbHPrffWTnD4TB9g+cccH/HOAOC0f1VS2as2G7 i3vKEKZblh23VE1T8iNcwEN9grS8RCG181QLcVsHRI6PNTQbTgmYyB2eUdmE+uwI ZFMLBaBWyy+T0dufHn28 =CRTY -----END PGP SIGNATURE-----
