Define simple expressions to filter not just by file and program name, but also by resulting values of collected stats. Support usual equality and inequality operators. Verdict, which is a boolean-like field can be also filtered either as 0/1, failure/success (with f/s, fail/succ, and failure/success aliases) symbols, or as false/true (f/t). Aliases are case insensitive. Currently this filtering is honored only in verification and replay modes. Comparison mode support will be added in next patch. Here's an example of verifying a bunch of BPF object files and emitting only results for successfully validated programs that have more than 100 total instructions processed by BPF verifier, sorted by number of instructions in ascending order: $ sudo ./veristat *.bpf.o -s insns^ -f 'insns>100' There can be many filters (both allow and deny flavors), all of them are combined.

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.
