Perhaps, but I had the opposite experience. I noticed by accident
that iostat (as included in Debian) suddenly had working extended
statistics. So there are *certainly* tools that get fixed by
2.4.19-pre7. I was pleasantly surprised.

Bummer, I'm using Debian, and iostat is in woody (frozen, about to
be released) - that means Debian users will have to wait to the
next release, another two years perhaps, before iostat gets working.

Why not keep it as it is, it's probably not going to break
anything as debian and redhat tools already know about this
apparently. 2.5 is about new features, 2.4 is about stability
and, though some might oppose, folding in stable patches that
have been in vendor kernels for months or years.

Mike.
