Disk IO statistics still buggy

The IO statistics displayed in /proc/partitions are still buggy, because
after some time, the value for the currently running requests gets too
high or too low (see the archives, look for "/proc/partitions").

Is anyone working on a fix?

Or does someone have an idea where the error might occur?
Which parts of the kernel play a role in starting/stopping block IO
requests (that are not part of ll_rw_blk.c) and might not handle the
accounting correctly?

I'd like to fix this and would appreciate any pointers, since after a
first look there is no obvious error in ll_rw_blk.c .

Thanks in advance,

Jochen Suckfuell
