David Vernet 895669fd0d scx: Fix exit selftest to use custom DSQ In commit `63fb3ec805` ("sched_ext: Allow only user DSQs for scx_bpf_consume(), scx_bpf_dsq_nr_queued() and bpf_iter_scx_dsq_new()"), we updated the consume path to only accept user DSQs, thus making it invalid to consume SCX_DSQ_GLOBAL. This selftest was doing that, so let's create a custom DSQ and use that instead. The test now passes: [root@virtme-ng sched_ext]# ./runner -t exit ===== START ===== TEST: exit DESCRIPTION: Verify we can cleanly exit a scheduler in multiple places OUTPUT: [ 12.387229] sched_ext: BPF scheduler "exit" enabled [ 12.406064] sched_ext: BPF scheduler "exit" disabled (unregistered from BPF) [ 12.453325] sched_ext: BPF scheduler "exit" enabled [ 12.474064] sched_ext: BPF scheduler "exit" disabled (unregistered from BPF) [ 12.515241] sched_ext: BPF scheduler "exit" enabled [ 12.532064] sched_ext: BPF scheduler "exit" disabled (unregistered from BPF) [ 12.592063] sched_ext: BPF scheduler "exit" disabled (unregistered from BPF) [ 12.654063] sched_ext: BPF scheduler "exit" disabled (unregistered from BPF) [ 12.715062] sched_ext: BPF scheduler "exit" disabled (unregistered from BPF) ok 1 exit # ===== END ===== Signed-off-by: David Vernet <void@manifault.com> Signed-off-by: Tejun Heo <tj@kernel.org>		History 2024-10-25 07:03:36 -10:00

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 reStructuredText 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.
