From 597ff72f3de850c3b93b41eca21732715d6ffc60 Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Sun, 4 Mar 2018 22:17:12 -0700 Subject: [PATCH] hyper-v: use GFP_KERNEL for hv_context.hv_numa_map The kzalloc function is called with GFP_ATOMIC. But according to driver call graph, it is not in atomic context, namely no spinlock is held nor in an interrupt handler. This GFP_ATOMIC is unnecessary, and replace with GFP_KERNEL.
