Possible bug: rtapi_mutex_get instead of rtapi_mutex_try ?

[Boris Skegin]

If I understand these lines correctly

'rtapi_mutex_get()' gets the mutex pointed to by 'mutex',
blocking if the mutex is not available. Because of this,
calling it from a realtime task is a "very bad" thing to
do.

then the cyclic tasks void lcec_read_master(void *arg, long period) and void lcec_write_master(void *arg, long period) may not give a mutex if the cycle time is not properly estimated and therefore exceeds the servo thread period?

int rtapi_mutex_try(unsigned long *mutex) as a workaround?
