| H A D | clocksource.c | f092eb34 Tue Dec 13 15:57:28 CST 2022 Paul E. McKenney <paulmck@kernel.org> clocksource: Improve read-back-delay message
When cs_watchdog_read() is unable to get a qualifying clocksource read
within the limit set by max_cswd_read_retries, it prints a message
and marks the clocksource under test as unstable. But that message is
unclear to anyone unfamiliar with the code:
clocksource: timekeeping watchdog on CPU13: wd-tsc-wd read-back delay 1000614ns, attempt 3, marking unstable
Therefore, add some context so that the message appears as follows:
clocksource: timekeeping watchdog on CPU13: wd-tsc-wd excessive read-back delay of 1000614ns vs. limit of 125000ns, wd-wd read-back delay only 27ns, attempt 3, marking tsc unstable
