From 52fd24ca1db3a741f144bbc229beefe044202cac Mon Sep 17 00:00:00 2001 From: Giridhar Pemmasani Date: Sat, 28 Oct 2006 10:38:34 -0700 Subject: [PATCH] __vmalloc with GFP_ATOMIC causes 'sleeping from invalid context' If __vmalloc is called to allocate memory with GFP_ATOMIC in atomic context, the chain of calls results in __get_vm_area_node allocating memory for vm_struct with GFP_KERNEL, causing the 'sleeping from invalid context' warning. This patch fixes it by passing the gfp flags along so __get_vm_area_node allocates memory for vm_struct with the same flags.
