Description
Some lustre code uses #include files coming from the e2fsprogs rpms, in particular the #include files in /usr/include/ext2fs. With the new version #include files from the latest v1.42.11.wc2 e2fsprogs some strictly user level code that uses those #incudes fail. The only thing that stops this bug from being a Blocker is that it isn't seen when building lustre in master. I think that's due to some of the restructuring of lustre #include that have happened lately in master. It is seen when building in b2_5 and earlier branches.
Pretty sure this is due to changes in e2fsprogs #includes as it is only seen when the new 1.42.11 is installed, not seen with 1.42.9 and earlier. example errors:

For some reason that's not entirely clear to me generic typedefs like __u32 aren't getting pulled in correctly when building strictly userspace code, like in lustre/utils, when #includes from /usr/include/ext2fs are used.
