Is it the reason that it only changes one byte at a time and the system can guarantee the atomic when updating one byte?
I think it's not atomic, I don't use atomic API here, because all mormal write are always changing the byte to the same value, if old value is read by concurrent writes, then this byte will be written multiple times, and I don't see any problems this way, just pure memory operation. Thanks, Kuai
