Frans Kaashoek dabbc348bc Maybe fix two races identified by rtm (thx!): ... - during exit(), hold p's parent lock and p's lock across all changes to p and its parent (e.g., reparenting and wakeup1). the lock ordering between concurrent exits of children, parent, and great parent might work out because processes form a tree. - in wakeup1() test and set p->state atomically by asking caller to have p locked. a correctness proof would be desirable.		2019-07-06 16:38:41 -04:00
