Subject: [PATCH 09/10] ext4: drop ext4_es_is_delonly()
Date: Sat, 1 Jun 2024 11:41:48 +0800 [thread overview]
Message-ID: <20240601034149.2169771-10-yi.zhang@huaweicloud.com> (raw)
In-Reply-To: <20240601034149.2169771-1-yi.zhang@huaweicloud.com>
From: Zhang Yi <yi.zhang@huawei.com>
Since we don't add delayed flag in unwritten extents, so there is no
difference between ext4_es_is_delayed() and ext4_es_is_delonly(),
just drop ext4_es_is_delonly().
