Subject: json: Make json_equal() compare objects correctly.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6e57173fab673b66870b3e181f09542da0d61587;p=openvswitch

json: Make json_equal() compare objects correctly.

The previous code checked only that JSON objects have members with the
same names.  This commit makes json_equal() also check that like-named
members have the same values.
