From b60cac14bb3c88cff2a7088d9095b01a80938c41 Mon Sep 17 00:00:00 2001 From: Jens Axboe <axboe@kernel.dk> Date: Tue, 21 Jun 2022 07:47:13 -0600 Subject: [PATCH] io_uring: fix merge error in checking send/recv addr2 flags 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.
