nfs41: minorversion support for nfs4_{init,destroy}_callback
move nfs4_init_callback into nfs4_init_client_minor_version and nfs4_destroy_callback into nfs4_clear_client_minor_version as these need to happen also when auto-negotiating the minorversion once the callback service for nfs41 becomes different than for nfs4.0 Signed-off-by: Benny Halevy <bhalevy@panasas.com> [nfs41: Fix checkpatch warning] Signed-off-by: Ricardo Labiaga <Ricardo.Labiaga@netapp.com> Signed-off-by: Benny Halevy <bhalevy@panasas.com> [Type check arguments of nfs_callback_up] Signed-off-by: Ricardo Labiaga <Ricardo.Labiaga@netapp.com> Signed-off-by: Benny Halevy <bhalevy@panasas.com> [nfs41: Backchannel: Remove FIXME comment] Signed-off-by: Ricardo Labiaga <Ricardo.Labiaga@netapp.com> Signed-off-by: Benny Halevy <bhalevy@panasas.com>
