Well, squashfs appends the rest of the name in squashfs_listxattr, so
it's not broken, just different. I have tried cleaning that up by
converting the list operation into something like this instead:

bool (*may_list)(struct dentry *dentry);

The xattr name would always be copied into the buffer in
iop->listxattr. But security_inode_listsecurity which is called from
vfs_getxattr as well as nfs4_xattr_list_nfs4_label was getting in the
way, and it's unclear to me how to best clean that up first.

Thanks,
Andreas
