hi steve-
downloaded your patches from 30 dec '03.
zeroing the RPC counters is a little outside the scope of my
patch, as i'm providing a whole new interface that is outside
the /proc/net/rpc/* hierarchy. this is work that might/should
go in separately from mine? (my patch will allow zeroing the
stats that i'm providing, which are different than the ones
already provided in /proc/net/rpc/nfs).
but one question: why do you use a hex value for this interface?
i thought /proc was supposed to be human-readable. why not use
"z" "zc" "zs" just like your nfsstat arguments so that one can
just as easily do:
echo "zs" > /proc/net/rpc/nfs
as well as
nfsstat -zs

Yes.. I agree... they are separate... and probably should stay separate.

Two reasons, one the debug interface uses a numeral interface and
two, I figured since nfsstat is already converting the command line
arguments into 'flag bits', reusing those flags bits to tell the kernel
which stats should be zeroed would be fairly clean and non intrusive
way to do it.

Good point... I guess I just assumed the nfsstat interface would be used.
