Merge tag 'for-linus-2021-01-24' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull misc fixes from Christian Brauner:
- Jann reported sparse complaints because of a missing __user
annotation in a helper we added way back when we added
pidfd_send_signal() to avoid compat syscall handling. Fix it.
- Yanfei replaces a reference in a comment to the _do_fork() helper I
removed a while ago with a reference to the new kernel_clone()
replacement
- Alexander Guril added a simple coding style fix
* tag 'for-linus-2021-01-24' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux:
kthread: remove comments about old _do_fork() helper
Kernel: fork.c: Fix coding style: Do not use {} around single-line statements
signal: Add missing __user annotation to copy_siginfo_from_user_any
