Subject: [RFC 0/5] leverage completion cache for poll requests
Date: Sat, 18 Sep 2021 03:38:15 +0800	[thread overview]
Message-ID: <20210917193820.224671-1-haoxu@linux.alibaba.com> (raw)

1st is a non-related code clean
2nd ~ 4th are fixes.
5th is the the main logic, I tested it with an echo-server, both in
single-shot mode and multishot mode poll, not much difference compared
to code before with regard to req/s. But that may be resulted from my
poor network knowledge, feel free to test it and leave comments.

Hao Xu (5):
  io_uring: return boolean value for io_alloc_async_data
  io_uring: code clean for io_poll_complete()
  io_uring: fix race between poll completion and cancel_hash insertion
  io_uring: fix lacking of EPOLLONESHOT
  io_uring: leverage completion cache for poll requests
