Merge branch 'bpf: Add detection of kfuncs.'
Alexei Starovoitov says: ==================== From: Alexei Starovoitov <ast@kernel.org> Allow BPF programs detect at load time whether particular kfunc exists. Patch 1: Allow ld_imm64 to point to kfunc in the kernel. Patch 2: Fix relocation of kfunc in ld_imm64 insn when kfunc is in kernel module. Patch 3: Introduce bpf_ksym_exists() macro. Patch 4: selftest. NOTE: detection of kfuncs from light skeleton is not supported yet. ==================== Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
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.
