[PATCH v2 4/5] perf report: Add --symbol-filter option

From: Namhyung Kim
Date: Fri Mar 16 2012 - 04:51:21 EST


Add new --symbol-filter command line option to set appropriate
filter string. Its short version is missing as I couldn't find
an ideal one and --filter option of perf record also has no
short version.
