From c225aa57ff4ffe715df4692676b77c815a337236 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Simon=20Holm=20Th=C3=B8gersen?= Date: Sun, 11 Jan 2009 22:34:01 -0500 Subject: ext4: fix wrong use of do_div MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit the following warning: fs/jbd2/journal.c: In function ‘jbd2_seq_info_show’: fs/jbd2/journal.c:850: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 3 has type ‘uint32_t’ is caused by wrong usage of do_div that modifies the dividend in-place and returns the quotient. So not only would an incorrect value be displayed, but s->journal->j_average_commit_time would also be changed to a wrong value! Fix it by using div_u64 instead.
