This patchset addresses z3fold stability issues under stress load,
primarily in the reclaim and free aspects. Besides, it fixes the
locking problems that were only seen in real-time kernel
configuration.

Vitaly Wool (2):
  z3fold: simplify freeing slots
  z3fold: stricter locking and more careful reclaim

Mike Galbraith (1):
  z3fold: Remove preempt disabled sections for RT

Thanks for addressing this!

(I'd appreciate Cc'ing me on this though since I was the one who
reported it initially...)
