H A D | dir.c | 1f5573cf Thu Nov 04 04:55:34 CDT 2021 Miklos Szeredi <mszeredi@redhat.com> ovl: fix warning in ovl_create_real()
Syzbot triggered the following warning in ovl_workdir_create() -> ovl_create_real():
if (!err && WARN_ON(!newdentry->d_inode)) {
The reason is that the cgroup2 filesystem returns from mkdir without instantiating the new dentry.
Weird filesystems such as this will be rejected by overlayfs at a later stage during setup, but to prevent such a warning, call ovl_mkdir_real() directly from ovl_workdir_create() and reject this case early.
