From 60bd08b6a70cc0d7413dc4f80e64f07e6c31d274 Mon Sep 17 00:00:00 2001
From: Andrei Vagin <avagin@google.com>
Date: Thu, 5 Dec 2024 22:17:38 +0000
Subject: [PATCH] vdso: handle vvar_vclock vma-s
The vvar_vclock was introduced by [1]. Basically, the old vvar vma has
been splited on two parts. In term of C/R, these two vma-s can be still
treated as one.
