From 63cf13b77ab785e87c867defa8545e6d4a989774 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Tue, 15 Jul 2008 13:22:49 -0700 Subject: [PATCH] generic ipi function calls: wait on alloc failure fallback When a GFP_ATOMIC allocation fails, it falls back to allocating the data on the stack and converting it to a waiting call. Make sure we actually wait in this case.
