Committer note: Split from a larger patch, this only dumps PERF_RECORD_COMPRESSED as unhandled, so that when we introduce the record part in the next patch, we don't see unhandled events when using 'perf record -D'. Changed it so that we dump the event if the handler is just a stub, i.e. for the case where we don't have ZSTD linked but we're processing a perf.data file generated by a tool with that linked. Also when failing to decompress we can't just dump the uncompressed event and return 0, we have to propagate the error.

README
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.
