The way this works is that 'is_locked' gets the value of the plock->lock and plock->lock gets the value of

'is_locked' which we just set to 'true'. Basically this is an atomic 'swap' command. If the lock had not yet been

reserved then its value would be 'false' and after the xchg() instruction finished 'is_locked' would have

'false'. If it had already been reserved then 'is_locked' would have 'true' after the xchg() instruction. Since
|

plock->lock was already 'true' and we just set it back to 'true' everything is ok. To see if we reserved the lock

we just need to check the value of 'is_locked' after this instruction finishes. */
