Add a few extra cases of global funcs with context arguments. This time rely on "arg:ctx" decl_tag (__arg_ctx macro), but put it next to "classic" cases where context argument has to be of an exact type that BPF verifier expects (e.g., bpf_user_pt_regs_t for kprobe/uprobe). Colocating all these cases separately from other global func args that rely on arg:xxx decl tags (in verifier_global_subprogs.c) allows for simpler backwards compatibility testing on old kernels. All the cases in test_global_func_ctx_args.c are supposed to work on older kernels, which was manually validated during development.

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.
