Subject: [PATCH 1/3] mm/memcg: Clean up obsolete enum charge_type
Date: Thu, 20 Aug 2020 09:03:48 -0400 [thread overview]
Message-ID: <20200820130350.3211-2-longman@redhat.com> (raw)
In-Reply-To: <20200820130350.3211-1-longman@redhat.com>
Since commit 0a31bc97c80c ("mm: memcontrol: rewrite uncharge API") and
commit 00501b531c47 ("mm: memcontrol: rewrite charge API") in v3.17, the
enum charge_type was no longer used anywhere. However, the enum itself
was not removed at that time. Remove the obsolete enum charge_type now.
