[$] A new kernel polling interface
Tuesday January 9, 2018. 10:56 PM , from LWN.net
Polling a set of file descriptors to see which ones can perform I/O without
blocking is a useful thing to do — so useful that the kernel provides three
different system calls (select(),
— plus some variants) to perform it. But sometimes three is not enough;
there is now a proposal circulating for a fourth kernel polling interface.
As is usually the case, the motivation for this change is performance.
