Thanks, applied.  I adjusted the commit message to make it clear what the patch
actually does:

commit 5befc19caec93f0088595b4d28baf10658c27a0f

    fscrypt: explicitly require that inode->i_blkbits be set

    Document that fscrypt_prepare_new_inode() requires inode->i_blkbits to
    be set, and make it WARN if it's not.  This would have made the CephFS
    bug https://tracker.ceph.com/issues/64035 a bit easier to debug.
