I over-trimmed this line: - bitmap_zero(iop->uptodate, PAGE_SIZE / SECTOR_SIZE); Looks like Christoph changed his mind sometime between that message and the first commit: 9dc55f1389f9569acf9659e58dd836a9c70df217 My THP patches convert the bit array to be per-block rather than per-sector, so this is all going to go away soon ;-) > https://lore.kernel.org/linux-xfs/20181215105155.GD1575@xxxxxx/
