From d2999c0fbcb2a84b0994ad3ec0d30c190ccd5e67 Mon Sep 17 00:00:00 2001 From: Michael Kelley Date: Wed, 14 Jan 2026 10:15:08 -0800 Subject: [PATCH] mshv: Add __user attribute to argument passed to access_ok() access_ok() expects its first argument to have the __user attribute since it is checking access to user space. Current code passes an argument that lacks that attribute, resulting in 'sparse' flagging the incorrect usage. However, the compiler doesn't generate code based on the attribute, so there's no actual bug. In the interest of general correctness and to avoid noise from sparse, add the __user attribute. No functional change.
