From d3f5ffcacd1528736471bc78f03f06da6c4551cc Mon Sep 17 00:00:00 2001 From: John Hubbard Date: Mon, 14 Dec 2020 19:07:45 -0800 Subject: mm: cleanup: remove unused tsk arg from __access_remote_vm Despite a comment that said that page fault accounting would be charged to whatever task_struct* was passed into __access_remote_vm(), the tsk argument was actually unused. Making page fault accounting actually use this task struct is quite a project, so there is no point in keeping the tsk argument. Delete both the comment, and the argument.
