With the dynamic debug feature, it is easy to enable all or some of them, and asks users to reproduce issues with extra debug. Many of these pr_debug() don't end with a new line, while no 'pr_cont()' are used in MPTCP code. So the goal was not to display multiple debug messages on one line: they were then not missing the '\n' on purpose. Not having the new line at the end causes these messages to be printed with a delay, when something else needs to be printed. This issue is not visible when many messages need to be printed, but it is annoying and confusing when only specific messages are expected, e.g. # echo "func mptcp_pm_add_addr_echoed +fmp" \ > /sys/kernel/debug/dynamic_debug/control # ./mptcp_join.sh "signal address"; \ echo "$(awk '{print $1}' /proc/uptime) - end"; \ sleep 5s; \ echo "$(awk '{print $1}' /proc/uptime) - restart"; \ ./mptcp_join.sh "signal address" 013 signal address (...) 10.75 - end 15.76 - restart 013 signal address [ 10.367935] mptcp:mptcp_pm_add_addr_echoed: MPTCP: msk=3D(...) (...) =3D> a delay of 5 seconds: printed with a 10.36 ts, but after 'restart' which was printed at the 15.76 ts. The 'Fixes' tag here below points to the first pr_debug() used without '\n' in net/mptcp. This patch could be split in many small ones, with different Fixes tag, but it doesn't seem worth it, because it is easy to re-generate this patch with this simple 'sed' command: git grep -l pr_debug -- net/mptcp | xargs sed -i "s/\(pr_debug(\".*[^n]\)\(\"[,)]\)/\1\\\n\2/g" So in case of conflicts, simply drop the modifications, and launch this command.
