Subject: jsonrpc: Make jsonrpc_error() internal.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c1ce8fbffb04e006a1698139132439ef0d7e57b2;p=openvswitch

jsonrpc: Make jsonrpc_error() internal.

This function is an implementation detail.  The JSONRPC unit test used it,
but not for any good reason, so this commit changes the test to avoid
using it.
