Subject: SUNRPC: export per-transport rpcbind netid's
X-Git-Tag: v2.6.24-rc1~1285^2~82
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4417c8c41a51a2ae95b2a2fa2811640b368c4151;p=linux-2.6

SUNRPC: export per-transport rpcbind netid's

The rpcbind (v3+) netid is provided by each RPC client transport. This fixes
an omission in IPv6 rpcbind client support, and enables future extension.
