From: Joe Perches Date: Tue, 1 Nov 2011 00:08:48 +0000 (-0700) Subject: mm/vmalloc.c: report more vmalloc failures X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=de7d2b567d040e3b67fe7121945982f14343213d;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git mm/vmalloc.c: report more vmalloc failures Some vmalloc failure paths do not report OOM conditions. Add warn_alloc_failed, which also does a dump_stack, to those failure paths. This allows more site specific vmalloc failure logging message printks to be removed.
