LONG_MAX.

It all fits perfectly:

static long wb_check_background_flush(struct bdi_writeback *wb)
{
if (over_bground_thresh()) {
struct wb_writeback_work work = {
.nr_pages = LONG_MAX,
.sync_mode = WB_SYNC_NONE,
.for_background = 1,
.range_cyclic = 1,
};

return wb_writeback(wb, &work);
}

return 0;
}
