From 09876ae73945ca69550ce2cbe0538de11997fd94 Mon Sep 17 00:00:00 2001 From: Kaixu Xia Date: Sat, 27 Aug 2022 17:02:50 +0800 Subject: [PATCH] mm/damon: simplify the parameter passing for 'check_accesses' Patch series "mm/damon: Simplify the damon regions access check", v2. This patchset simplifies the operations when checking the damon regions accesses. This patch (of 2): The parameter 'struct damon_ctx *ctx' isn't used in the functions __damon_{p,v}a_check_access(), so we can remove it and simplify the parameter passing.
