Subject: [PATCH 2/9] vfs: ignore error on forced remount
Date: Tue, 05 Oct 2010 12:31:10 +0200 [thread overview]
Message-ID: <20101005103135.841553506@szeredi.hu> (raw)
In-Reply-To: <20101005103108.288743609@szeredi.hu>
[-- Attachment #1: vfs-fix-force-remount-readonly.patch --]
[-- Type: text/plain, Size: 843 bytes --]
From: Miklos Szeredi <mszeredi@suse.cz>
On emergency remount we want to force MS_RDONLY on the super block
even if ->remount_fs() failed for some reason.
