From 371376750fce0abb09b1aa3fd8ae7025813a3488 Mon Sep 17 00:00:00 2001 From: Joonsoo Kim Date: Tue, 26 Jul 2016 15:23:52 -0700 Subject: [PATCH] tools/vm/page_owner: increase temporary buffer size Page owner will be changed to store more deep stacktrace so current temporary buffer size isn't enough. Increase it.
