From c85d2cfc5e24e6866b56c7253fd4e1c7db35986c Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 20 Nov 2025 11:40:15 -0700 Subject: [PATCH] io_uring/cmd_net: fix wrong argument types for skb_queue_splice() commit 46447367a52965e9d35f112f5b26fc8ff8ec443d upstream. If timestamp retriving needs to be retried and the local list of SKB's already has entries, then it's spliced back into the socket queue. However, the arguments for the splice helper are transposed, causing exactly the wrong direction of splicing into the on-stack list. Fix that up.
