Subject: remove sun_path field from isc_netaddr
X-Git-Tag: v9.21.15~19^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6601a301233b03847f6da06077db6cb819c8969a;p=thirdparty%2Fbind9.git

remove sun_path field from isc_netaddr

The sun_path field is not used anymore, and consumes over a hundred
bytes for every isc_netaddr_t object. Remove it.

As isc_netaddr_t is used in cfg_obj_t, in some huge configuration trees
(e.g., a million zones), the gain is almost 1GB of resident memory.
