Add a selftest that tries to trigger a situation where two timer callbacks are attempting to cancel each other's timer. By running them continuously, we hit a condition where both run in parallel and cancel each other. Without the fix in the previous patch, this would cause a lockup as hrtimer_cancel on either side will wait for forward progress from the callback. Ensure that this situation leads to a EDEADLK error. Signed-off-by: Kumar Kartikeya Dwivedi <memxor@xxxxxxxxx> --- Changelog: * Add missing timer_lockup__destroy. * Fix inline declarations (Alexei). * Shorten pthread_create line (Alexei). * Fix type of map value parameter to time cb (Alexei). * Add a counter to skip test if race does not reproduce (Alexei).
Did some small cleanups while applying, and ran several times w/o issues. Applied, thanks Kumar!
