Then bitmap_limit will be calculated to\n0. md_super_write() will be called with 0 size.\nThat means the first 4k sb area of node 1 will never be updated\nthrough filemap_write_page().\nThis bug causes hang of mdadm/clustermd_tests/01r1_Grow_resize.\n\nHere use (pg_index % bitmap->storage.file_pages) to make calculation\nof bitmap_limit correct.",
