I'm working my way through these changes now. 1, 2, 15 and 16 applied.

We discussed briefly your change 
0011-Replace-per-proc-counters-of-loggable-locks-with-per.patch.

I don't see how that helps at all. The objective of lock counters was to
know if we can skip acquiring an LWlock on all lock partitions. This
change keeps the lock counters yet acquires the locks we were trying to
avoid. This change needs some justification since it is not a bug fix.
