[lustre-discuss] Lustre Client on Fedora 23

[Dilger, Andreas]

This is really more of a topic for lustre-devel, so I've CC'd that list and we can move future conversation over there.

This particular issue looks related to changes made by Andreas Gruenbacher (xattr maintainer) that went upstream.  Probably best to follow the commits in "git log drivers/staging/lustre/lustre/llite" and port those patches back to master.

Cheers, Andreas
