From 00dcffaebf7b4ab0524c56694c22de6b0eb22feb Mon Sep 17 00:00:00 2001 From: Marcelo Ricardo Leitner Date: Tue, 11 Aug 2015 19:22:25 -0300 Subject: [PATCH] dlm: fix reconnecting but not sending data There are cases on which lowcomms_connect_sock() is called directly, which caused the CF_WRITE_PENDING flag to not bet set upon reconnect, specially on send_to_sock() error handling. On this last, the flag was already cleared and no further attempt on transmitting would be done. As dlm tends to connect when it needs to transmit something, it makes sense to always mark this flag right after the connect.
