I have the same comment as on the xfs patch. If the filesystem has opted
out of acls and SB_POSIXACL isn't set in sb->s_flags then
posix_acl_create() is a nop. Why bother placing it under an ifdef?

It adds visual noise and it implies that posix_acl_create() actually
does something even if the filesystem doesn't support posix acls.

Unless this actually fixes something I'd drop this patch too.
