This would be VERY trivial to add - the intent was to allow a query of
the CIFS/SMB3 specific inode metatada via a user xattr (the attribute
was defined as user.DosAttrib).   Probably less than 10 lines of code
to finishup below the following in fs/cifs/xattr.c

if (strncmp(ea_name, CIFS_XATTR_DOS_ATTRIB, 14) == 0) {
cifs_dbg(FYI, "attempt to query cifs inode metadata\n");
/* revalidate/getattr then populate from inode */
