There is currently only 1 'perf data' command, but supporting extra
commands was breaking the help output. Simplify for now so that the help
output is correct.
Before:
$ perf data -h
Usage: perf data [<common options>] <command> [<options>]
$ perf data
Usage:
perf data [<common options>] <command> [<options>]
Available commands:
convert - converts data file between formats
After:
$ perf data
Usage: perf data convert [<options>]
-f, --force don't complain, do it
-i, --input <file> input file name
-v, --verbose be more verbose
--all Convert all events
--to-ctf ... Convert to CTF format
--to-json ... Convert to JSON format
--tod Convert time to wall clock time
$ perf data -h
Usage: perf data convert [<options>]
-f, --force don't complain, do it
-i, --input <file> input file name
-v, --verbose be more verbose
--all Convert all events
--to-ctf ... Convert to CTF format
--to-json ... Convert to JSON format

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
