djm pushed a commit to branch master
in repository openssh.
commit 9d883a1ce4f89b175fd77405ff32674620703fb2
Author: djm at openbsd.org <djm at openbsd.org>
Date: Wed Sep 26 01:48:57 2018 +0000
upstream: s/process_mux_master/mux_master_process/ in mux master
function names,
Gives better symmetry with the existing mux_client_*() names and makes
it more obvious when a message comes from the master vs client (they
are interleved in ControlMaster=auto mode).
no functional change beyond prefixing a could of log messages with
__func__ where they were previously lacking.
