From: Eric Sandeen Date: Mon, 26 May 2008 16:29:46 +0000 (-0400) Subject: ext4: enable barriers by default X-Git-Tag: v2.6.26-rc6~29^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=571640cad3fda6475da45d91cf86076f1f86bd9b;p=pandora-kernel.git ext4: enable barriers by default I can't think of any valid reason for ext4 to not use barriers when they are available; I believe this is necessary for filesystem integrity in the face of a volatile write cache on storage. An administrator who trusts that the cache is sufficiently battery- backed (and power supplies are sufficiently redundant, etc...) can always turn it back off again. SuSE has carried such a patch for ext3 for quite some time now. Also document the mount option while we're at it.
