From c44b31c263798ec34614dd394c31ef1a2e7e716e Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 12 Oct 2021 11:57:28 -0400 Subject: SUNRPC: Change return value type of .pc_decode 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_decode return only true or false.
