NFSD: Get response size before operation for all RPCs

Browse source

NFSD usess PAGE_SIZE as the reply size estimate for RPCs which don't
support op_rsize_bop(), A PAGE_SIZE (4096) is larger than many real
response sizes, eg, access (op_encode_hdr_size + 2), seek
(op_encode_hdr_size + 3).

This patch just adds op_rsize_bop() for all RPCs getting response size.

An overestimate is generally safe but the tighter estimates are probably
better.
