Test: kernel testing for notification
Perform notification tests on both domains.
Scenarios where low notifications are wanted need further synchronization
since multiple low notifications can be sent between resume_consumer
and the lttng stop command. This problem can be addressed by suspending
the generation of events. This is achieved by the use of signal-aware
background shells and the use of lttng-test kernel module or
gen-ust-events as events generator.
These background shells are controlled by signal SIGUSR1 and
provide their states via a state file. If the file is present the
application is suspended and does not generate events, otherwise events
are generated.
