Gregory Nutt	11a635dcb3 mm/iob: IOB free notifier should accept the work queue ID as a paramter. The notification may need to run on either the high- or low- priority work queue. sched/work: Change the default priority of the low-priority work queue to 100.	6 years ago
Gregory Nutt	af0ee3c8f7 sched/wqueue: Add an option to work queue notifier so that the notification can occur on different work queues.	6 years ago
Gregory Nutt	9d3148406c Signals were not a good choice of IPC to implement the poll function for several reasons: In order to handle the asynchrnous poll-related event, a substantial amount of state information is needed. Signals are only capable of passing minimal amounts of data. There are also complexities with performing kernel space signal handlers in kernel space code that is better to avoid. So, instead of signals, the equivalent logic was converted to run via a callback that executes on the high-priority work queue.	6 years ago
Gregory Nutt	20814acad2 sched/signal: In signal notification facility, use sigqueue() to notify vs. kill(). With sigqueue, we can pass more info (but still not enough).	6 years ago
