Hi Linus,

Two different fixes in here:

- Fix for a potential NULL pointer deref for links with async or drain
  marked (Pavel)

- Fix for not properly checking RLIMIT_NOFILE for async punted
  operations. This affects openat/openat2, which were added this cycle,
  and accept4. I did a full audit of other cases where we might check
  current->signal->rlim[] and found only RLIMIT_FSIZE for buffered
  writes and fallocate. That one is fixed and queued for 5.7 and marked
  stable.

Please pull!
