Kevin,

Can you try this quick hack?

diff --git a/kernel/capability.c b/kernel/capability.c
index e57d1aa..4088610 100644
- --- a/kernel/capability.c
+++ b/kernel/capability.c
@@ -109,7 +109,7 @@ out:

}
- - while (i < _LINUX_CAPABILITY_U32S) {
+ while (0 && (i < _LINUX_CAPABILITY_U32S)) {
if (pE.cap[i] || pP.cap[i] || pP.cap[i]) {
/* Cannot represent w/ legacy structure */
return -ERANGE;

Thanks

Andrew
