Woke up early and had another look at this.  Looks like a much more
widespread problem.  Based on a quick grep an uncaffeinated brain:

9p	no s_bdi
afs	no s_bdi
ceph	creates its own s_bdi
cifs	no s_bdi
coda	no s_bdi
ecryptfs no s_bdi
exofs	no s_bdi
fuse	creates its own s_bdi?
gfs2	creates its own s_bdi?
jffs2	patch exists
logfs	fixed now
ncpfs	no s_bdi
nfs	creates its own s_bdi
ocfs2	no s_bdi
smbfs	no s_bdi
ubifs	creates its own s_bdi

I excluded all filesystems that appear to be read-only, block device
based or lack any sort of backing store.  So there is a chance I have
missed some as well.
