What happened to DIOCGDINFO? Fwd: [package - head-amd64-default][misc/e2fsprogs-libblkid] Failed for e2fsprogs-libblkid-1.42.12 in build

Greetings,

I am getting new reports of package build failures on head (i386 and
amd64 have reported these so far):

I haven't been watching 11-HEAD too closely, has this DIOCGDINFO symbol
been relocated to a different header, removed (because the feature is
going away -- and which would be the replacement), or is this a
temporary failure (inadvertent error)?

To the best of my knowledge, and without retrying builds, the package
builds fine on 8/9/10.

Thanks,
Matthias
