I did go through something about an Distinctive lock observe, so I have a feasible concept that if the thread resumes and executes the STREX, the os observe leads to this get in touch with to fall short which may be detected plus the loop can be re-executed utilizing the new value in the process (department again to LDREX), Am i right here ?
