fs: dlm: don't close socket on invalid message (0ea47e4d) · Commits · 戴 / test

This patch doesn't close sockets when there is an invalid dlm message received. The connection will probably reconnect anyway so. To not close the connection will reduce the number of possible failtures. As we don't have a different strategy to react on such scenario just keep going the connection and ignore the message.
