I note in our bugzilla that we still have an open bug against the
uninit_groups patch related to resize2fs, related to the fact that
resize2fs allocating new inodes or blocks will likely not clear
the UNINIT flags from the groups it is working on:

https://bugzilla.lustre.org/show_bug.cgi?id=12002

I verified that the code to disable resize2fs is still in the "next"
branch, so there is no immediate danger, but it also means that
filesystems with uninit_groups enabled can not be resized.

Cheers, Andreas
