When we get to it ;) Seriously though, EA support is being planned for, it's
just lower on the priority list than things like sparse file support, online
resize, directory improvements, etc.

Not much - downloading the latest kernel code and editing fs/ocfs2/ to add
this :) Patches are always welcome, and actually I think EA is a good
candidate for someone who wants to contribute but doesn't yet understand the
all the cluster stuff.

As a first pass, a simple attribute block, pointed to by an __le64 in the
dinode would work fine. More improvements and optimizations could come after
that.

Don't they get EA from ext3? Anyway, yeah Lustre does some really cool stuff
- I think we're pretty different in the types of clusters we serve though :)
