From 6581f6e35f7d0338f699fce660adb48e863f2b59 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 13 Dec 2011 00:16:50 +0900 Subject: perf report: Document '--call-graph' for optional print_limit argument The '--call-graph' command line option can receive undocumented optional print_limit argument. Besides, use strtoul() to parse the option since its type is u32.
