Subject: [PATCH] drivers/xen/xenbus: Replace deprecated strcpy in xenbus_transaction_end
Date: Sun, 12 Oct 2025 21:55:09 +0200 [thread overview]
Message-ID: <20251012195514.39003-2-thorsten.blum@linux.dev> (raw)
strcpy() is deprecated; use strscpy() instead. Fix the function comment
and use bool instead of int while we're at it.
