Definitely. I couldn't even keep up reading his CVS update mails. :-)

Don't hold your breath though. Things tend to go a little slower than

Fine. :-)

BTW, have you tried the R5 Pro CD with your session module? It's the 
only multi-session CD I have at hand and unfortunately only its first 
session is reported. The first time I tested was after some changes, 
but none to the session module and none that could possibly have such a 
side effect (I hope at least ;-). Here's, what the test program prints, 
when debug output is enabled for disk_scanner (I added some more output 
to track the problem down) and the session module (and a fs/testfs 
module that does nothing). Of interest are perhaps only the last 10-15 
lines, but for sake of completeness... ;-)
