Write Barrier for ext3 and ext4
Until Linux kernel 2.6.31, write barriers were not supported (fully supported in 2.6.33). This means that the guarantee against filesystem corruption offered by journaled file systems like ext3 and XFS was negated under some circumstances. Many Linux distributions, with the notable exception of SUSE and Fedora, turn off protective barriers by default anyway, to prevent performance degradation.
