    Subject[PATCH 7/9] perf lock: Document lock info subcommand
    Date
    From: Namhyung Kim <namhyung@gmail.com>

    The commit 26242d859c9be ("perf lock: Add "info" subcommand for dumping
    misc information") added the subcommand but missed documentation. Add
    it. Also update stale 'trace' subcommand to 'script'.
