Just throwing this out there, in case it wasn't already obvious: it is
entirely possible that the kernel client is doing something trivially
wrong that is mucking this all up as well. We've never played with
SELinux, and I'm not sure if there are any requirements beyond xattr
support from the FS. For POSIX ACLs, for instance, there is a bunch of
boilerplate code that has to be wired up, even though the fs doesn't
actually do anything besides store the xattrs and pass them to the VFS
helpers. (Possibly an easy kernel project, if anyone is interested.)
