commit 021189e32ba507832b5e821e5cda8a2889225955
Author: Ralph Boehme <slow at samba.org>
Date:   Fri Feb 17 08:10:53 2017 +0100

    vfs_streams_xattr: use fsp, not base_fsp
    
    The base_fsp's fd is always -1 as it's closed after being openend in
    create_file_unixpath().
    
    Additionally in streams_xattr_open force using of SMB_VFS_FSETXATTR() by
    sticking the just created fd into the fsp (and removing it afterwards).
