Alexander Aring b97f85259f fs: dlm: implement delayed ack handling ... This patch changes that we don't ack each message. Lowcomms will take care about to send an ack back after a bulk of messages was processed. Currently it's only when the whole receive buffer was processed, there might better positions to send an ack back but only the lowcomms implementation know when there are more data to receive. This patch has also disadvantages that we might retransmit more on errors, however this is a very rare case. Tested with make_panic on gfs2 with three nodes by running: trace-cmd record -p function -l 'dlm_send_ack' sleep 100 and trace-cmd report | wc -l Before patch: - 20548 - 21376 - 21398 After patch: - 18338 - 20679 - 19949 Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com>		2021-08-19 11:33:03 -05:00
