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!
