From 39d80c33a068d9fa63a36c3b2c0d718d38440dd1 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 6 Oct 2008 21:37:44 -0400 Subject: [PATCH] ext4: Avoid double dirtying of super block in ext4_put_super() While reading code I noticed that ext4_put_super() dirties the superblock bh twice. It is always done in ext4_commit_super() too. Remove the redundant dirty operation. Should be a nop semantically.
