Subject: [PATCH v3] Add kernel_dgram_send() into logging_send_syslog_msg()
Date: Mon, 15 Apr 2019 02:12:02 +0000	[thread overview]
Message-ID: <20190415021153.8218-1-dsugar@tresys.com> (raw)

This patch is based on comments from previous a patch to
remove the many uses of kernel_dgram_send() and incorporate
it into logging_send_syslog_msg().

v2 - enclose in ifdef for redhat
v3 - rebase this patch on e41def136a9b2246ceba671421caafa893814cdb
