Date: Mon, 17 Sep 2007 10:31:31 +0200 From: Avi Kivity <avi@...ranet.com> To: kvm-devel@...ts.sourceforge.net Cc: linux-kernel@...r.kernel.org, Rusty Russell <rusty@...tcorp.com.au> Subject: [PATCH 049/104] KVM: Use kmem_cache_free for kmem_cache_zalloc'ed objects From: Rusty Russell <rusty@...tcorp.com.au> We use kfree in svm.c and vmx.c, and this works, but it could break at any time. kfree() is supposed to match up with kmalloc().
