Detailed Description

Linux implementation details.

bio uses iouring on Linux.

For network, it detects whether bind or listen can be submitted through iouring and fallback to the synchronous version instead as those calls typically do not block.

For bio_platform_update, it uses a futex if there is support. Otherwise an eventfd is used instead.
