There are some more bugs too:


RCU stalls, fix has been in rcu/urgent for 7 days:
https://git.kernel.org/cgit/linux/kernel/git/paulmck/linux-rcu.git/commit/?h=rcu/urgent&id=789cbbeca4eb7141cbd748ee93772471101b507b


blk-mq bio merging (still no good fix available):
https://lkml.org/lkml/2014/10/9/729
(The fix sitting in the block tree:
https://git.kernel.org/cgit/linux/kernel/git/axboe/linux-block.git/commit/?h=for-3.18/core&id=764f612c6c3c231b9c12cfae7c328ccc9c453258
is wrong according to that message.)


Stalls when using nohz, requires series of six patches to fix that
didn't make 3.17 and weren't marked for -stable:
