HULK inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBY4CK ---------------------------- The md_bitmap_status() function incorrectly returns for external bitmaps, preventing statistics collection when a valid superblock page exists. Remove the external bitmap check as the statistics should be available regardless of bitmap storage location when sb_page is present. Note: "bitmap_info.external" here refers to a bitmap stored in a separate file (bitmap_file), not to external metadata.
