io_uring: handle connect -EINPROGRESS like -EAGAIN (87f80d62) · Commits · 戴 / test

Right now we return it to userspace, which means the application has to poll for the socket to be writeable. Let's just treat it like -EAGAIN and have io_uring handle it internally, this makes it much easier to use. Signed-off-by:
