Allow tests to have their own set of sub-tests. Also add ability to do test/subtest selection using `-t <test-name>/<subtest-name>` and `-n <test-nums-set>/<subtest-nums-set>`, as an extension of existing -t/-n selector options. For the <test-num-set> format: it's a comma-separated list of either individual test numbers (1-based), or range of test numbers. E.g., all of the following are valid sets of test numbers: - 10 - 1,2,3 - 1-3 - 5-10,1,3-4 '/<subtest' part is optional, but has the same format. E.g., to select test #3 and its sub-tests #10 through #15, use: -t 3/10-15. Similarly, to select tests by name, use `-t verif/strobe`: $ sudo ./test_progs -t verif/strobe #3/12 strobemeta.o:OK #3/13 strobemeta_nounroll1.o:OK #3/14 strobemeta_nounroll2.o:OK #3 bpf_verif_scale:OK Summary: 1/3 PASSED, 0 FAILED Example of using subtest API is in the next patch, converting bpf_verif_scale.c tests to use sub-tests.

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.
