I think it may be nicer to take the rcu read lock at the call site rather than in ipc_obtain_object(), to make the rcu read lock/unlock sites pair up more nicely. Either that or make an inline ipc_release_object function that pairs up with ipc_obtain_object() and just does an rcu_read_unlock().
I started on a patch series to untangle the IPC locking, so it will be a little more readable, and easier to maintain. It is a slower approach than Davidlohr's, as in, it will take a little longer to put a patch series together, but I hope it will be easier to debug... I hope to post a first iteration of the series by the middle of next week. -- All rights reversed -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
