We are interested in implementing UID/GID based NRS policies to see what we can get. In order to do this, it is essential to add the UID/GID of the processes that trigger the RPCs into to the request bodies. We implement this by filling the UID/GID into the padding of the request body and then get a 'UID/GID Round Robin' policy by changing CRRN policy (the attaced patch). We know it is not a good implementation though it works fine for testing. And we know it is not easy to implement a good one because we need to handle global user ID over entire cluster. Any advice or idea? Thanks!
Improvement

LU-16077 Cannot use tbf to filter brw request per effective uid/gid, inode attr ids is used instead
