Nothing really, other than that they use semaphores to avoid lockdep :-/ I think I know how to annotate this, after Alan Stern explained all the use cases, but I haven't come around to implementing it. Hope to do that soonish. Another real semaphore user is XFS, they really use the down/up asymmetry that semaphores allow, last time I spoke with Dave Chinner he didn't know a way around this. - 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/
