Back in 2005, Alex sent a patch to monitor journal activity through procfs:
http://marc.info/?l=linux-ext4&m=113538565128617&w=2
We have been using this patch for more than 1 year and it is very useful
for investigating performance issues.
Does anybody know why this patch hasn't found its way into the mainline?
Maybe it could be merged in jbd2?
