My program is occasionally seeing slow page faults. latencytop says they're slow because they're waiting for read access to mmap_sem, but latencytop isn't showing any other thread in the process blocking.
Is there any straightforward way to find out who called down_write on mmap_sem when down_read is slow? --Andy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
