Subject: Fix: unload all kernel modules on sessiond exit
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=f50b6d556820ba724597c9fe760677cfbd1c9ceb;p=lttng-tools.git

Fix: unload all kernel modules on sessiond exit

Stopping a root lttng-sessiond that has loaded kernel modules currently
leaves some modules loaded, add them in the correct order to allow
unloading them all.
