Command
# ./perf report -i /tmp/111 -D > /dev/null
emits an error message when a sample for event CRYPTO_ALL in the
perf.data file does not contain any raw data. This is ok. Do not
trigger this warning when the sample in the perf.data files does not
contain any raw data at all. Check for availability of raw data for all
events and return if none is available.
Output before:
# ./perf report -i /tmp/111 -D > /dev/null
Invalid CRYPTO_ALL raw data encountered
Invalid CRYPTO_ALL raw data encountered
Invalid CRYPTO_ALL raw data encountered
#
Output after:
# ./perf report -i /tmp/111 -D > /dev/null
#
Fixes: b539deafba ("perf report: Add s390 raw data interpretation for PAI counters")

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.
