[PATCH] vmalloc: Add __get_vm_area_caller()
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

linux-mm, lkml
We have get_vm_area_caller() and __get_vm_area() but not __get_vm_area_caller() On powerpc, I use __get_vm_area() to separate the ranges of addresses given to vmalloc vs. ioremap (various good reasons for that) so in order to be able to implement the new caller tracking in /proc/vmallocinfo, I need a "_caller" variant of it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> --- I want to put into powerpc-next patches relying into that, so if the patch is ok with you guys, can I stick it in powerpc.git ? include/linux/vmalloc.h | 3 +++ mm/vmalloc.c | 8 ++++++++ 2 files changed, 11 insertions(+)
