Merge tag 'for-linus-2020-04-18' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull thread fixes from Christian Brauner:
"A few fixes and minor improvements:
- Correctly validate the cgroup file descriptor when clone3() is used
with CLONE_INTO_CGROUP.
- Check that a new enough version of struct clone_args is passed
which supports the cgroup file descriptor argument when
CLONE_INTO_CGROUP is set in the flags argument.
- Catch nonsensical struct clone_args layouts at build time.
- Catch extensions of struct clone_args without updating the uapi
visible size definitions at build time.
- Check whether the signal is valid early in kill_pid_usb_asyncio()
before doing further work.
- Replace open-coded rcu_read_lock()+kill_pid_info()+rcu_read_unlock()
sequence in kill_something_info() with kill_proc_info() which is a
dedicated helper to do just that"
