[PATCH V1 22/32] char: qio_channel_socket_accept reuse fd |
Date: |
Thu, 30 Jul 2020 08:14:26 -0700 |
From: Mark Kanda <mark.kanda@oracle.com>
Add an fd argument to qio_channel_socket_accept. If not -1, the channel
uses that fd instead of accepting a new socket connection. All callers
pass -1 in this patch, so no functional change.
