    ovl: filter of trusted xattr results in audit · 5c2e9f34
    Mark Salyzyn authored
    When filtering xattr list for reading, presence of trusted xattr
    results in a security audit log.  However, if there is other content
    no errno will be set, and if there isn't, the errno will be -ENODATA
    and not -EPERM as is usually associated with a lack of capability.
    The check does not block the request to list the xattrs present.
    
    Switch to ns_capable_noaudit to reflect a more appropriate check.
