From 3e6fb8e94329270c70ea00867112a2c6f348207f Mon Sep 17 00:00:00 2001 From: Joonsoo Kim <iamjoonsoo.kim@lge.com> Date: Wed, 3 Dec 2014 10:39:20 +0900 Subject: [PATCH] Documentation: describe trace_buf_size parameter more accurately I'm stuck into panic that too litte free memory is left when I boot with trace_buf_size parameter. After digging into the problem, I found that trace_buf_size is the size of trace buffer on each cpu rather than total size of trace buffer. To prevent victim like me, change description of trace_buf_size parameter more accurately.
