[PATCH] selftests: kvm: make hardware_disable_test less verbose

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



hardware_disable_test produces 512 snippets like
...
 main: [511] waiting semaphore
 run_test: [511] start vcpus
 run_test: [511] all threads launched
 main: [511] waiting 368us
 main: [511] killing child

and this doesn't have much value, let's just drop these fprintf().
Restoring them for debugging purposes shouldn't be too hard.
