The fix for this is given as http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=eee5cc2702929fd41cce28058dc6d6717f723f87 Neither the patch author (Al Viro) nor our kernel security team can see how this patch prevents the async io related soft lockup. Is there any more information about this that can be shared here or elsewhere? jch
