- if (nd->dentry && nd->dentry->d_sb &&

Hmm. You are right. Something is wrong. Possibly my interpretation :)

I am trying hard but can not reproduce the problem with unpatched kernel either.

Anyway, the symptoms were the same as before with 2.4.x and ESTALE.
I would bet that I'd see exactly that if somehow the kernel has got
the FS_REVAL_DOT for Coda. The system was sane otherwise.
The only thing I did not check was that it was really ESTALE.
Watch better next time Ivan.
(and no, I was not dreaming, I've got cut-n-paste logs... :)

I have not changed anything remarkable in the setup since the test,
except of course the reboots after kernel changes.

Sorry for pointing in a wrong direction, I'll keep you posted if I see
the problem again.
