hm, I wonder why I didn't notice that.

yup.  Fixed a bunch of those, let one slip through.

I don't immediately see how to fix this one, actually:

static inline int ecryptfs_statfs(struct super_block *sb, struct kstatfs *buf)
{
	return vfs_statfs(ecryptfs_superblock_to_lower(sb), buf);
}

Once we've run ecryptfs_superblock_to_lower() to get the "lower
superblock", we need to turn that back into a vfsmount for vfs_statfs()..

(and that function needn't have been inlined - it's only ever called
indirectly)

I think I'll be dropping the fs-cache patches (again) fairly soon.  They're
intrusive, quite some effort to carry, they're not getting adequate review
(afaict) and there doesn't seem to be a lot of demand for them, sorry.
