And this build regression has been pushed upstream now, as of:

   8520eeaa1235: Merge git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6

and it is triggering for me too:

   fs/built-in.o: In function `cifs_getxattr':
   (.text+0xc518e): undefined reference to `get_cifs_acl'

The regression got introduced by:

   fbeba8bb16d7: cifs: Handle extended attribute name cifs_acl to generate cifs acl blob (try #4)

Which introduced the new CIFS_ACL option.

Thanks,
