"I am using the latest ext4 patches and the tip of the e2fsprogs
git repository. Hopefully when we get the bulk of the patches
merged into the mainline kernel after the 2.6.26 ships and the
2.6.27 merge window opens, and after I ship out e2fsprogs 1.41 (I
have one work-in-progress pre-release, with another coming soon),
it’ll be ready for much more wide-spread testing."
