linux - EXT4 In kernel 3.5 Gets CRC32 Meta-Data

Posted by Michael Larabel on June 01, 2012 The pull request for the EXT4 file-system in the Linux 3.5 kernel and there's one prominent new feature. The EXT4 file-system with the Linuux 3.5 kernel will now support CRC32 check-sums on the meta-data fields. This work was done by Darrick J Wong to further improve the reliability of the EXT4 file-system. The EXT4 on-disk layout has changed to support the extended meta-data check-summing. Aside from this new feature, there's the usual list of bug-fixes and clean-ups. The EXT4 Linux 3.5 pull request can be viewed at

Cool, i never thought about the idea to extend the ext4 since zfs is the only way to go for my head ;-).

Don't get me wrong, it is no killerfeature but it is nice to read that ext4 gets extended.
