Subject: [PATCH] io_uring: handle connect -EINPROGRESS like -EAGAIN
Date: Tue, 3 Dec 2019 11:25:23 -0700
Message-ID: <> (raw)

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.
