From: Dave Chinner Date: Fri, 23 Jul 2010 10:49:41 +0000 (+0200) Subject: ext3: default to ordered mode X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=aa32a796389b;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git ext3: default to ordered mode data=writeback mode is dangerous as it leads to higher data loss and stale data exposure when systems crash. It should not be the default, especially when all major distros ensure their ext3 filesystems default to ordered mode. Change the default mode to the safer data=ordered mode, because we should be caring far more about avoiding stale data exposure than performance.
