Subject: [PATCH] ext4: make ext4_mb_initialize_context return void
Date: Thu, 27 Oct 2022 11:24:35 +0800	[thread overview]
Message-ID: <20221027032435.27374-1-guoqing.jiang@linux.dev> (raw)

Change the return type to void since it always return 0, and no need
to do the checking in ext4_mb_new_blocks.
