ROOT NFS fixes ...

ROOT NFS fixes ...

[Herbert Pötzl]

Hi Marcelo!

just verified that the NFS root bug-fix was not
included in 2.4.22-pre9, unfortunately I have 
to ask you again, why you do not want to fix 
this issue in 2.4.22 ...

I do not understand why Trond obviously is
ignoring my mails, regarding this particular
issue, maybe he is just too busy to look at 
four twoline changes, and more, I do not 
understand why this isn't accepted into the 
marcelo kernel tree, as it obviously fixes a
misbehaviour?

please explain!

It is okay for me, if your argumentation goes 
like "I don't like you, that's reason enough
for me to not include your patches ...", but I
would like to know ...

best,
Herbert

I do not consider the patch critical enough.

Get it in 2.5 first, then come back :)

No, this is not a joke, at all.

Let me repeat: I (and Trond) do not consider this patch critical.

Ok, I'm wrong. I just read Trond's mail saying the patch is OK.

I'll apply it to -pre10.

hmm, maybe it _is_ too early to do this ;)
but on the other hand, I'm a fearless creature ...

What do you mean too early ?

Trond is OK with it, it seems.

err, correct me if I am totally wrong here but does "ROOT NFS fixes" means 
somewhat like

append="nfsroot=10.0.0.7:/home/nfsroot \
    ip=10.0.0.254:10.0.0.7:10.0.0.7:255.255.255.0:temp:eth0:off root=/dev/nfs"

does not work w/o the fix?

ciao, Marc

ROOT NFS fixes ...

[Herbert Pötzl]

Hi Trond!

please have a look at the attached patch, which
addresses the root=/dev/wossname issue, when ROOT_NFS
is configured. this is a NFS only issue, and IMHO
fixes an erroneous behaviour.

if it seems okay to you, please let Marcelo know,
so he could add this patch to the next -pre kernel

MTIA,
Herbert
