From: wang di <di.w...@intel.com> If ll_iget fails during inode initialization, especially during striped directory lookup after creation failed, then it should clear stripe MD before make_bad_inode(), because make_bad_inode() will reset the i_mode, which can cause ll_clear_inode() skip freeing those stripe MD.
