From: Artem Bityutskiy Subject: [PATCH 3/8] ext2: write superblock only once on unmount Date: Wed, 21 Mar 2012 18:14:30 +0200 Message-ID: <1332346475-1441-4-git-send-email-dedekind1@gmail.com> References: <1332346475-1441-1-git-send-email-dedekind1@gmail.com> Cc: Ext4 Mailing List , Linux FS Maling List , Linux Kernel Maling List To: Jan Kara Return-path: In-Reply-To: <1332346475-1441-1-git-send-email-dedekind1@gmail.com> Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org From: Artem Bityutskiy Currently on unmount if we are mounted R/W, we first write the superblock to the media if it is dirty, and then write it again, which is not optimal. This patch makes ext2 write the superblock on unmount less times.
