Nevermind, alloc_file export had been restored in mainline already.
So just pull from the same place, same branch (
git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ master
), there's just that one commit on top of mainline.

What happened: in absence of CONFIG_TPMFS_POSIX_ACL, shmem_mknod() had
code that boiled down to
	error = 0; /* shmem_acl_init(...), actually */
	if (error)
		cleanup
and Christoph's patch had put all that chunk under ifdef.  Which was not
an equivalent transformation, since we could arrive there with non-zero
error.  Old code used to set it to 0, new one left as-is.
