argh. 13 arguments to single function ?!
Currently the call site looks like:
trace_balance_dirty_pages(wb,
sdtc->thresh,
sdtc->bg_thresh,
sdtc->dirty,
sdtc->wb_thresh,
sdtc->wb_dirty,
dirty_ratelimit,
task_ratelimit,
pages_dirtied,
period,
min(pause, 0L),
start_time);
Just pass sdtc as a pointer instead.
Then another wb argument will be fine.
