From: Jann Horn jannh@google.com Date: Mon, 19 Feb 2018 18:50:39 +0100 Subject: x86/mm: Remove stale comment about KMEMCHECK
From: Jann Horn jannh@google.com
commit 3b3a9268bba62b35a29bafe0931715b1725fdf26 upstream.
This comment referred to a conditional call to kmemcheck_hide() that was here until commit 4950276672fc ("kmemcheck: remove annotations").
Now that kmemcheck has been removed, it doesn't make sense anymore.
