One piece of work done for Lustre was the ability to submit "units" like
K, M, G for sizes to sysfs files. This was developed before string helpers
was created and the code for Lustre is well very ugly. So I rewrote it
in the style of string helpers and it can be handly for other things as 
well such as module parameters setting. Lustre does have certain features
in it debugging system that can applied to the linux kernel debugging
system. That is more down the road. Their are few others like the crypto
wrapper for alder. I don't see why that can't be mainstream.

I was looking to see what you plan to work on. I wanted to avoid 
duplicating work. Some things I know of done already are listed under:

https://jira.hpdd.intel.com/browse/LU-9855
https://jira.hpdd.intel.com/browse/LU-10257
https://jira.hpdd.intel.com/browse/LU-10994

Their are a few others I have to hunt down but these are the major ones.
