commit 518549c120e671c4906f77d1802b97e9b23f673a upstream.
When running fstest generic/423 with sfu mount option, it was being skipped due to inability to create sockets:
generic/423 [not run] cifs does not support mknod/mkfifo
which can also be easily reproduced with their af_unix tool:
./src/af_unix /mnt1/socket-two bind: Operation not permitted
Fix sfu mount option to allow creating and reporting sockets.
