From ab620620bf426af110093c5921888c0a4bf86ab4 Mon Sep 17 00:00:00 2001 From: "Ritesh Harjani (IBM)" Date: Thu, 18 Aug 2022 10:34:39 +0530 Subject: fs/buffer: drop useless return value of submit_bh submit_bh always returns 0. This patch drops the useless return value of submit_bh from __sync_dirty_buffer(). Once all of submit_bh callers are cleaned up, we can make it's return type as void.
