Sigh... Anyway, actual commit id is cfaefc95bfa7eb92dd837ea9fb38bc84e62d79b5 and curl 'https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/patch/?id=cfaefc95bfa7eb92dd837ea9fb38bc84e62d79b5' definitely finds it, so commit is there. #syz test: git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git cfaefc95bfa7eb92dd837ea9fb38bc84e62d79b5
