I mean, squash the comment only. |
if xtimer_set spins the callback is executed in the thread context. comment to explain irq_disable and when this line could be removed (when xtimer stops executing the callback funtion from thread context)
Only yields and change threads status when thread was removed from mutex list.
because of pr RIOT-OS#11759: not all boards check for is_in_irq when thread_yield_higher

xtimer.c:xtimer_mutex_lock_timeout()(the tracking pr: #11660 )This pr improves the _mutex_timeout() function.

sched_switch(thread_yield_higherbefore) when the thread was unlocked.And ensure interrupt are disabled because it modifies a mutex. (if
xtimer_setspins the callback is executed in the thread context.)This pr also changes the comment of
