From 1e1c65e03ec817a64153751150f6691db9842acd Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Mon, 21 Apr 2008 13:48:24 +0200 Subject: [PATCH] KVM: remove long -> void *user -> long cast kvm_dev_ioctl casts the arg value to void __user *, just to recast it again to long. This seems unnecessary. According to objdump the binary code on x86 is unchanged by this patch.
