[PATCH v2 0/6] coroutine: new sleep/wake API


From: Paolo Bonzini
Subject: [PATCH v2 0/6] coroutine: new sleep/wake API
Date: Mon, 17 May 2021 12:05:42 +0200

This is a revamp of the qemu_co_sleep* API that makes it easier to
extend the API: the state that is needed to wake up a coroutine is now
part of the public API instead of hidden behind a pointer-to-pointer;
the API is made more extensible by pushing the rest of QemuCoSleepState
into local variables.

In the future, this will be extended to introduce a prepare/sleep/cancel
API similar to Linux's prepare_to_wait/schedule/finish_wait functions.
For now, this is just a nice refactoring.
