From: Namhyung Kim <[email protected]>
The -s (--sort) option was processed after normal option parsing so that
it cannot call the parse_options_usage() automatically. Currently it
calls usage_with_options() which shows entire help messages for event
option. Fix it by showing just -s options.
$ perf report -s help
Error: Unknown --sort key: `help'
usage: perf report [<options>]
-s, --sort <key[,key2...]>
sort by key(s): pid, comm, dso, symbol, ...
