Frans Kaashoek	67702cf706	Checkpoint switching to per-process locks, in attempt clarify xv6's ... locking plan, which is a difficult to understand because ptable lock protects many invariants. This implementation has a bug: once in a while xv6 unlocks a proc lock that is locked by another core.	2019-07-02 09:14:47 -04:00
