[PATCH 0/2] fdmon-poll: reset npfd when upgrading to fdmon-epoll

Posted by Stefan Hajnoczi 3 years, 8 months ago

Fix an assertion failure when aio_poll() is called in a aio_disable_external()
region. The failure happens when fdmon-poll is first upgraded to fdmon-epoll
and then downgraded again due to aio_disable_external().
