Subject: [PATCH] ext4: remove redundant variable has_bigalloc in ext4_fill_super
Date:   Wed, 15 Apr 2020 15:25:42 +0800
Message-Id: <1586935542-29588-1-git-send-email-kaixuxia@tencent.com>
Sender: linux-ext4-owner@vger.kernel.org
Precedence: bulk

From: Kaixu Xia <kaixuxia@tencent.com>

We can use the ext4_has_feature_bigalloc() function directly to check
bigalloc feature and the variable has_bigalloc is reduncant, so remove
it.
