mm/page-writeback.c: place "not" inside of unlikely() statement in wb_domain_writeout_inc()
The likely/unlikely profiler noticed that the unlikely statement in
wb_domain_writeout_inc() is constantly wrong. This is due to the "not"
(!) being outside the unlikely statement. It is likely that
dom->period_time will be set, but unlikely that it wont be. Move the
not into the unlikely statement.
