Merge tag 'io_uring-5.6-20200320' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
"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"
* tag 'io_uring-5.6-20200320' of git://git.kernel.dk/linux-block:
io_uring: make sure accept honor rlimit nofile
io_uring: make sure openat/openat2 honor rlimit nofile
io_uring: NULL-deref for IOSQE_{ASYNC,DRAIN}
