generic/377 failing, xattr: security.SMACK64

Hello!

JFYI

generic/377 test  failing after enabling CONFIG_SECURITY_SMACK in kernel:

switching off CONFIG_SECURITY_SMACK in kernel (or via kernel command
line security=none) make this test pass successfully.


A quick fix is probably mark SMACK as unsupported (yet) and grep smack
attrs out after calling to sort, for example (makes test as OK):
