Subject: [PATCH v6 01/10] userfaultfd/hugetlbfs: avoid including userfaultfd_k.h in hugetlb.h
Date: Mon, 3 May 2021 11:07:28 -0700 [thread overview]
Message-ID: <20210503180737.2487560-2-axelrasmussen@google.com> (raw)
In-Reply-To: <20210503180737.2487560-1-axelrasmussen@google.com>
Minimizing header file inclusion is desirable. In this case, we can do
so just by forward declaring the enumeration our signature relies upon.
