hi， there may be a bug in ext4_read_inline_dir() function with inline_data feature. when I recursion call a sys_old_readdir to read a direntry's sub_dentry,I find that the ext4_read_inline_dir return the len of the inline_data ,but in the no inline_data case,it will return 0.It is inconsistent. So I try to make a patch to fix it.
