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

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
