Subject: [PATCH 6/6] io_uring: allow NOP opcode in IOPOLL mode
Date: Thu, 21 Apr 2022 02:13:45 -0700	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>

This is useful for tests so that IOPOLL can be tested without requiring
files. NOP is acceptable in IOPOLL as it always completes immediately.
