vould you please update the changelog with the new syntax examples?
also Documentation/perf-config.txt wasn't updated

anyway.. any chance we could use syntax here that would follow
the sysctl style?

sysctl [options] [variable[=value]] [...]
sysctl -p [file or regexp] [...]

# display current config
perf config

# display current config plus all keys with default values
perf config -a

# display key value:
perf config report.queue

# set key value:
perf config report.queue=100M

# remove key (not in sysctl)
perf config -r report.queue
