[PATCH 0/2 v4] nfs: return nfs4 compound header status on op header decoding error

[Benny Halevy]

Trond,  following our conversation during the Connectathon
I reduced this patch as much as possible and restricted the
use of the compound header status to cases where op_hdr
decoding hit an error.

This is needed for nfs41 for graceful fallback when trying
to mount a 4.0 server with 4.1.  In this case the server
returns no ops and the hdr status is set to
NFS4ERR_MINOR_VERS_MISMATCH.

Please consider these patches:

[PATCH 1/2] nfs: return nfs4 compound header status on op header decoding error
[PATCH 2/2] nfs: remove incorrect usage of nfs4 compound response hdr.status

Thanks,

Benny
