Subject: [PATCH 1/9] rv: Fix __user specifier usage in extract_params()
Date: Tue, 12 May 2026 16:02:42 +0200	[thread overview]
Message-ID: <20260512140250.262190-2-gmonaco@redhat.com> (raw)
In-Reply-To: <20260512140250.262190-1-gmonaco@redhat.com>

The attributes variables extracted from syscalls in the helper are both
defined with the __user specifier although only the actual pointer to
user data should be marked.

Remove the __user specifier from attr.

Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202604150820.Ny143u6X-lkp@intel.com
Fixes: b133207deb72 ("rv: Add nomiss deadline monitor")
