[1] changed the below condition, which made f2fs_put_page() voided.
This patch reapplies the AL's resolution in -next from [2].
- if (S_ISDIR(old_inode->i_mode)) {
+ if (old_is_dir && old_dir != new_dir) {
old_dir_entry = f2fs_parent_dir(old_inode, &old_dir_page);
if (!old_dir_entry) {
if (IS_ERR(old_dir_page))
[1] 7deee77b993a ("f2fs: Avoid reading renamed directory if parent does not change")
[2] https://lore.kernel.org/all/20231220013402.GW1674809@ZenIV/
