Subject: [PATCH]i[next] io_uring: remove redundant check on force_nonblock
Date: Tue,  5 May 2020 10:33:43 +0100	[thread overview]
Message-ID: <[email protected]> (raw)

From: Colin Ian King <[email protected]>

The check on force_nonblock is redundant as this is performed
several statements earlier and also returns with -EAGAIN. Remove
the redundant check.
