Subject: rcutorture: meaning of "End of test: RCU_HOTPLUG"
Hi, guys
While running rcutorture tests with "onoff_interval", some tests
failed and results show like:
=====================================================================
[ 316.354501] srcud-torture:--- End of test: RCU_HOTPLUG: nreaders=1
nfakewriters=4 stat_interval=60 verbose=2 test_no_idle_hz=1
shuffle_interval=3 stutter=5 irqreader=1 fq\
s_duration=0 fqs_holdoff=0 fqs_stutter=3 test_boost=1/0
test_boost_interval=7 test_boost_duration=4 shutdown_secs=0 stall_cpu=0
stall_cpu_holdoff=10 stall_cpu_irqsoff=0 n_ba\
rrier_cbs=0 onoff_interval=3 onoff_holdoff=0
====================================================================
I am wondering that meaning of "RCU_HOTPLUG". Is it expected because
cpu hotplug is enabled in the test? Or just represents another type of
failure?
Thanks,
Su
