Subject: [PATCH] cxl: don't manipulate the mm.mm_users field directly
Date: Wed, 10 Mar 2021 18:44:05 +0100 [thread overview]
Message-ID: <20210310174405.51044-1-ldufour@linux.ibm.com> (raw)
It is better to rely on the API provided by the MM layer instead of
directly manipulating the mm_users field.
