Subject: [PATCH AUTOSEL 5.18 37/53] io_uring: fix merge error in checking send/recv addr2 flags
Date: Mon, 27 Jun 2022 22:18:23 -0400	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>

From: Jens Axboe <[email protected]>

[ Upstream commit b60cac14bb3c88cff2a7088d9095b01a80938c41 ]

With the dropping of the IOPOLL checking in the per-opcode handlers,
we inadvertently left two checks in the recv/recvmsg and send/sendmsg
prep handlers for the same thing, and one of them includes addr2 which
holds the flags for these opcodes.

Fix it up and kill the redundant checks.
