I think this is esialy fixed by simply dropping both batches messing with it - we should have the new locks protecting it in places once inode_lock is dropped. The other one is the clean up inode reference counting patch, which sounds like it should be earlier in the series so that we have the helpers in place before touching all places that opencode an inode reference count increment. Thanks forpicking up the work on this while Nick is travelling and some more comments on the individual patches will follow. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
