Subject: [PATCH] hugetlbfs: remove meaningless variable avoid_reserve
Date: Sat, 16 Jan 2021 04:26:44 -0500	[thread overview]
Message-ID: <20210116092644.42697-1-linmiaohe@huawei.com> (raw)

The variable avoid_reserve is meaningless because we never changed its
value and just passed it to alloc_huge_page(). So remove it to make code
more clear that in hugetlbfs_fallocate, we never avoid reserve when alloc
hugepage yet.
