The default rlimit RLIMIT_MEMLOCK is 64KB. In certain cases, e.g. in a test machine mimicking our production system, this test may fail due to unable to charge the required memory for prog load: $ ./test_dev_cgroup libbpf: load bpf program failed: Operation not permitted libbpf: failed to load program 'cgroup/dev' libbpf: failed to load object './dev_cgroup.o' Failed to load DEV_CGROUP program ... Changing the default rlimit RLIMIT_MEMLOCK to unlimited makes the test pass. This patch also fixed a problem where when bpf_prog_load fails, cleanup_cgroup_environment() should not be called since setup_cgroup_environment() has not been invoked. Otherwise, the following confusing message will appear: ... (/home/yhs/local/linux/tools/testing/selftests/bpf/cgroup_helpers.c:95: errno: No such file or directory) Opening Cgroup Procs: /mnt/cgroup.procs ...

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
