    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.
