From 861404536a3af3c39f1b10959a40def3d8efa2dd Mon Sep 17 00:00:00 2001 From: Yu Zhao Date: Wed, 24 Feb 2021 12:08:21 -0800 Subject: mm/swap.c: don't pass "enum lru_list" to trace_mm_lru_insertion() The parameter is redundant in the sense that it can be extracted from the "struct page" parameter by page_lru() correctly.
