Subject: [PATCH 6/6] io_uring/rw: remove dead file == NULL check
Date: Tue,  6 Feb 2024 09:22:52 -0700	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>

Any read/write opcode has needs_file == true, which means that we
would've failed the request long before reaching the issue stage if we
didn't successfully assign a file. This check has been dead forever,
and is really a leftover from generic code.
