So I've been noodling over Andreas' patches to support 32-bit extents,
as well as glancing at the 48-bit and 64-bit patches, and I've come to
an initial plan for how to fold this into e2fsprogs in the most
ABI-preserving, backwards compatible way possible. This does mean that

I've released the 2.6.22-rc4-ext4-1 tree, which can be downloaded from
the usual place:
http://ftp.kernel.org/pub/linux/kernel/people/tytso/ext4-patches
This is just a rebase versus 2.6.22-rc4, and reflects the bugfix patches
that have been accepted into mainline.
The hg repository located at:
http://thunk.org/hg/e2fsprogs

could test it and let me know if they find any embarassing bugs, I would
greatly appreciate it. It can also be found at:
People may have noticed that e2fsprogs 1.40 and roughly a week later
e2fsprogs 1.40.1 have been released, while there hasn't been any

e2fsprogs 1.40, I have moved the e2fsprogs development activity over to

E2fsprogs 1.40.2 has been released. It can be downloaded from one of
the following sites:

The need for fixing byte-swapped filesystems is long-gone, and this is

byte-swapped filesystem in in about 9 years.

Factor out code to clear a bogus inode and update e2fsck's internal

Linus and adds a number of cleanup patches. It also adds support for

sectors to eliminate one stupid (and easy to fix) large file scalability
limit.
