This patchset change to check epoll's enablement first before nodes
iteration to improve aio_poll()'s performance.
Also fix a wrong comment of mirror_start().
Yaowei Bai (2):
block: mirror: fix wrong comment of mirror_start
aio: improve aio_poll performance by checking epoll only once
aio
As epoll whether enabled or not is a global setting, we can just
check it only once rather than checking it with every node iteration.
Through this we can avoid a lot of checks when epoll is not enabled.
