From 28615e6eed152f2fda5486680090b74aeed7b554 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Tue, 20 May 2025 21:27:55 -0700 Subject: [PATCH] mm/damon/Kconfig: enable CONFIG_DAMON by default As of this writing, multiple major distros including Alma, Amazon, Android, CentOS, Debian, Fedora, and Oracle are build-enabling DAMON (set CONFIG_DAMON[1]). Enabling it by default will save configuration setup time for the current and future DAMON users. Build-enabling DAMON does not introduce a real risk since it makes no behavioral change by default. It requires explicit user requests to do anything. Only one potential risk is making the size of the kernel a little bit larger. On a production-purpose configuration, it increases the resulting kernel package size by about 0.1 % of the final package file. I believe that's too small to be a real problem in common setups. Hence, the benefit of enabling CONFIG_DAMON outweighs the potential risk. Set CONFIG_DAMON by default.
