Unfortunately the mtd-utils appear to be currently not very well maintained and
a number of patches submitted to the mailing list got more or less neglected.

However there _is_ currently an effort on the way to do a major overhaul/cleanup of
the mtd-utils that also incorporates a bunch of fixes that accumulated on the mailing
list, also including this patch.

You can take a look at the current progress here:
