tracing: make testing syscall events a separate configuration
Parag noticed that the number of event tests has increased tremendously:
grep "Testing event" dmesg.31rc9 |wc -l
100
grep "Testing event" dmesg.31git |wc -l
1172
This is due to the testing of every syscall event when ftrace self
test is enabled. This adds a bit more time to kernel boot up and can
affect development by slowing down the time it takes between reboots.
This option makes the testing of the syscall events into a separate
config, to still be able to test most of ftrace internals at boot up
but not have to wait for all the syscall events to be tested.
The syscall event testing only tests the enabling and disabling of
the trace point, since the syscalls are not executed. What really needs
to be done is to somehow have a userspace tool test the syscall tracepoints
as well.
