Variable err is initialized with 0. As a result, the return value may be 0 even if get_zeroed_page() fails to allocate memory. This patch fixes the bug, initializing err with "-ENOMEM". v1 is reviewed by: Juergen Gross <jgross@xxxxxxxx> Signed-off-by: Pan Bian <bianpan2016@xxxxxxx> --- drivers/xen/xenbus/xenbus_probe.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/xen/xenbus/xenbus_probe.c b/drivers/xen/xenbus/xenbus_probe.c index 33a31cf..8178d5b 100644 --- a/drivers/xen/xenbus/xenbus_probe.c +++ b/drivers/xen/xenbus/xenbus_probe.c @@ -702,7 +702,7 @@ static int __init xenbus_probe_initcall(void) */ static int __init xenstored_local_init(void) { - int err = 0; + int err = -ENOMEM; unsigned long page = 0; struct evtchn_alloc_unbound alloc_unbound; -- 1.9.1 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx https://lists.xen.org/xen-devel
