Subject: [PATCH] x86: Fix PTI comment in entry_SYSCALL_64
Date: Fri, 9 Feb 2018 09:06:38 -0800 [thread overview]
Message-ID: <20180209170638.15161-1-namit@vmware.com> (raw)
The comment is confusing since the path is taken when
PAGE_TABLE_ISOLATION is disabled (while the comment says it is not
taken).
