libfs: support RENAME_NOREPLACE in simple_rename()
This is trivial to do: - add flags argument to simple_rename() - check if flags doesn't have any other than RENAME_NOREPLACE - assign simple_rename() to .rename2 instead of .rename Filesystems converted: hugetlbfs, ramfs, bpf. Debugfs uses simple_rename() to implement debugfs_rename(), which is for debugfs instances to rename files internally, not for userspace filesystem access. For this case pass zero flags to simple_rename(). Signed-off-by: Miklos Szeredi <mszeredi@redhat.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Alexei Starovoitov <ast@kernel.org>
