Commit d96c36004e31 ("tracing: Fix FTRACE_RECORD_RECURSION_SIZE Kconfig
entry") removed a hidden tab because it apparently showed breakage in
some third-party kernel config parsing tool.
It wasn't clear what tool it was, but let's make sure it gets fixed.
Because if you can't parse tabs as whitespace, you should not be parsing
the kernel Kconfig files.
In fact, let's make such breakage more obvious than some esoteric ftrace
record size option. If you can't parse tabs, you can't have page sizes.
Yes, tab-vs-space confusion is sadly a traditional Unix thing, and
'make' is famous for being broken in this regard. But no, that does not
mean that it's ok.
I'd add more random tabs to our Kconfig files, but I don't want to make
things uglier than necessary. But it *might* bbe necessary if it turns
out we see more of this kind of silly tooling.

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 reStructuredText 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.
