From d1f6222c4978817712e0f2825ce9e830763f0695 Mon Sep 17 00:00:00 2001 From: Dylan Yudaken Date: Fri, 5 Aug 2022 04:54:50 -0700 Subject: [PATCH] io_uring: fix io_recvmsg_prep_multishot sparse warnings Fix casts missing the __user parts. This seemed to only cause errors on the alpha build, or if checked with sparse, but it was definitely an oversight.
