do_IRQ: stack overflow

[Kiernan, Michael]

Can anyone help me debug/(fix!) a stack overflow? (see attachment). 

redhat 7.3, dual xeon 2.8GHz
2.4.20-20.7bigmem, but also occurs with 2.4.18-27.7bigmem and 
non-bigmem versions. 

Thanks,
Mike

...but does the latest 2.4.22-bk snapshot?

I'd prefer not avoid having to convert all the nfs_fh and nfs_fattr
structures to use dynamic allocation if at all possible. Removing the
unused readdirplus-specific fields in struct nfs_entry is by far my
first choice for a solution. Now that has been done, then we can start
to worry about the remaining cases.

So has anybody ever seen stack overflow errors in any of the other
functions that allocate nfs_fh/nfs_fattr on the stack? That would be
mainly in nfs_lookup() and nfs_lookup_revalidate().

Cheers,
  Trond
