Date: Fri, 1 May 2020 11:59:50 +0530 From: Ritesh Harjani <riteshh@...ux.ibm.com> To: linux-ext4@...r.kernel.org Cc: "Paul E . McKenney" <paulmck@...nel.org>, linux-fsdevel@...r.kernel.org, Jan Kara <jack@...e.com>, tytso@....edu, "Aneesh Kumar K . V" <aneesh.kumar@...ux.ibm.com>, Ritesh Harjani <riteshh@...ux.ibm.com> Subject: [RFC 08/20] ext4: mballoc: Simplify error handling in ext4_init_mballoc() This patch simplifies error handling logic in ext4_init_mballoc(), by adding all the cleanups at one place at the end of that function. There should be no functionality change in this patch.
