Merge tag 'pidfd-fixes-v5.2-rc1' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux
Pull pidfd fixes from Christian Brauner: "This fixes two bugs: - The first one reported by Linus whereby the pidfd-metadata binary was not placed in a .gitignore file. - The second one is rather urgent and fixes a locking issue found by syzkaller. What happened is that during process creation we need to check whether the cgroup we are in allows us to fork. To perform this check the cgroup needs to guard itself against threadgroup changes and takes a lock. Prior to CLONE_PIDFD the cleanup target "bad_fork_free_pid" would also need to release said lock. That's not true anymore since CLONE_PIDFD so this is fixed here. Syzkaller has tested the patch and was not able to reproduce the issue" * tag 'pidfd-fixes-v5.2-rc1' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux: fork: do not release lock that wasn't taken samples: add .gitignore for pidfd-metadata
