I'm afraid that this isn't something that OpenAFS can fix; it's either an upstream kernel bug or an intentional kernel incompatibility with all non-GPL modules (even open-source ones like OpenAFS) depending on which way you want to look at it. I'm afraid the only solution is to disable CONFIG_LOCK_DEBUG (or something like that; I'm not sure of the exact setting, but it's one of the debugging ones) so that __rcu_read_unlock isn't marked GPL-only. I assume this is a custom 2.6.30 kernel build? If this is a stock Debian kernel, we're going to have much more serious problems. :/ -- Russ Allbery ([email protected]) <http://www.eyrie.org/~eagle/> -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
