Subject: [PATCH] perf lock: Remove redundant word 'contention' in help message
Before:
# perf lock -h
Usage: perf lock [<options>] {record|report|script|info|contention|contention}
-D, --dump-raw-trace dump raw trace in ASCII
-f, --force don't complain, do it
-i, --input <file> input file name
-v, --verbose be more verbose (show symbol address, etc)
--kallsyms <file>
kallsyms pathname
--vmlinux <file> vmlinux pathname
After:
# perf lock -h
Usage: perf lock [<options>] {record|report|script|info|contention}
-D, --dump-raw-trace dump raw trace in ASCII
-f, --force don't complain, do it
-i, --input <file> input file name
-v, --verbose be more verbose (show symbol address, etc)
--kallsyms <file>
kallsyms pathname
--vmlinux <file> vmlinux pathname
Fixes: 528b9cab3b81 ("perf lock: Add 'contention' subcommand")
