Subject: [PATCH v2 1/3] ext4: Delete ext4_kvzvalloc()
Date: Fri, 27 Dec 2019 17:05:21 +0900	[thread overview]
Message-ID: <20191227080523.31808-2-naoto.kobayashi4c@gmail.com> (raw)
In-Reply-To: <20191227080523.31808-1-naoto.kobayashi4c@gmail.com>

Since we're not using ext4_kvzalloc(), delete this function.
