Sometimes, the on-disk metadata might be invalid due to user interrupts, storage failures, or other unknown causes. In that case, z_erofs_map_blocks_iter() may still return a valid m_llen while other fields remain invalid (e.g., m_plen can be 0). Due to the return value of z_erofs_scan_folio() in some path will be ignored on purpose, the following z_erofs_scan_folio() could then use the invalid value by accident. Let's reset m_llen to 0 to prevent this. Link: https://lore.kernel.org/r/20240629185743.2819229-1-hsiangkao@linux.alibaba.com Signed-off-by: Gao Xiang <hsiangkao@linux.alibaba.com> |
