Subject: [PATCH] lib/flex_proportions.c: aging counts when fraction smaller than max_frac/FPROP_FRAC_BASE
Date: Wed, 6 May 2020 14:21:28 +0800	[thread overview]
Message-ID: <1588746088-38605-1-git-send-email-tan.hu@zte.com.cn> (raw)

If the given type has fraction smaller than max_frac/FPROP_FRAC_BASE,
__fprop_inc_percpu_max should follow the design formula and aging
fraction too.
