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. ... Squashed commit of the following: Fix up some final compile isses. net/netdev: Convert the network down notification logic to use the new wqueue-based notification factility. net/udp: Convert the UDP readahead notification logic to use the new wqueue-based notification factility. net/tcp: Convert the TCP readahead notification logic to use the new wqueue-based notification factility. mm/iob: Convert the IOB notification logic to use the new wqueue-based notification factility. sched/wqueue: Signals are not good IPCs to support the target poll functionality for several reasons including the amount of data that can be passed with a signal and in the fact that in protected and kernel modes, user threads executing signal handlers in protected, kernel memory is problematic. Instead, convert the same logic to perform the notifications via function callback on the high priority work queue.		2018-09-09 15:01:44 -06:00

netpacket	This commit brings in a fragmentary, experimental implementation of NETLINK sockets. There is not too much to that socket support on this initial commit, just the netlink socketer framework. However, I decided to bring it into master because there is a enough that I would not want to lose what is in place. And since it is dependent on CONFIG_EXPERIMENATL, its presence on master should be innocuous.	2018-08-03 13:22:36 -06:00
