From 420be4edefe503f8dbd6ab914b11a57a0d339660 Mon Sep 17 00:00:00 2001 From: Chengyang Fan Date: Tue, 4 May 2021 18:37:48 -0700 Subject: mm/ksm: remove unused parameter from remove_trailing_rmap_items() Since commit 6514d511dbe5 ("ksm: singly-linked rmap_list") was merged, remove_trailing_rmap_items() doesn't use the 'mm_slot' parameter. So remove it, and update caller accordingly.
