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
