Subject: [PATCH] mm/page-writeback: Update the comment of Dirty position control
Date: Tue, 11 May 2021 13:26:26 +0800 [thread overview]
Message-ID: <20210511052626.19005-1-wuchi.zero@gmail.com> (raw)
As the value of pos_ratio_polynom() clamp between 0 and
2LL << RATELIMIT_CALC_SHIFT, the global control line should be
consistent with it.
