SUNRPC: Change return value type of .pc_encode

2021-10-13T15:34:49+00:00

Returning an undecorated integer is an age-old trope, but it's not clear (even to previous experts in this code) that the only valid return values are 1 and 0. These functions do not return a negative errno, rpc_stat value, or a positive length. Document there are only two valid return values by having .pc_encode return only true or false.

SUNRPC: Replace the "__be32 *p" parameter to .pc_encode

2021-10-13T15:34:49+00:00

The passed-in value of the "__be32 *p" parameter is now unused in every server-side XDR encoder, and can be removed. Note also that there is a line in each encoder that sets up a local pointer to a struct xdr_stream. Passing that pointer from the dispatcher instead saves one line per encoder function.
