Subject: mm/damon: simplify the parameter passing for 'prepare_access_checks'
Date: Tue, 13 Sep 2022 17:11:24 +0800
Patch series "mm/damon: code simplifications and cleanups".
This patchset contains some code simplifications and cleanups for DAMON.
This patch (of 4):
The parameter 'struct damon_ctx *ctx' isn't used in the functions
__damon_{p,v}a_prepare_access_check(), so we can remove it and simplify
the parameter passing.
