Hi,

I've checked my e-mail backlog and I don't seem to see any e-mails
from you.  What e-mail address did you use?

I saw the ping of the github issue #146 so it's been on my to do list.
I've noted the patch at https://github.com/viavi-ab/e2fsprogs and I'll
try to take look at it this week.

In general, though, the best place to send patches or bug reports is
to send them to linux-ext4@...r.kernel.org mailing list.  Other ext4
developers can review patches for both e2fsprogs and the ext4 kernel
code, and send suggestions to patch submitters when they are sent to
the linux-ext4 mailing list.

In contrast, I'm the only person who monitors the github project,
which happens only on a best-efforts basis, with patches sent to the
linux-ext4 mailing list are much higher priority, for which I have
tools like patchwork and b4 to track and apply outstanding patches.

Cheers,
