Recursive unfair reader lock may guarantee deadlock-safety, but remember, it adds a higher probability of live-locking the write_lock. Which is another argument to keep this separate to cpu hotplug only. -- Steve _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
