There's been over a dozen random tiny cleanup patches to jbd.  I've
been waiting for them to die down, and for me to have time, and I was
going to batch them into a single commit (I'm not fond of a whole
series of random cleanup patches that just fix spelling mistakes and
other random code churn).  If someone would like to get to that before
we, it would be much appreciated.
