Now that we don't need to print the IP/ADDR for callindent the DSO is
also not printed. It's useful for some cases, so add an own DSO printout
for callindent for the case when IP/ADDR is not enabled.
Before:
% perf script --itrace=cr -F +callindent,-ip,-sym,-symoff,-addr

(in the kernel case of course it's not very useful, but it's important
with user programs where symbols are not unique)

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
