Alan Maguire says: ==================== bpf: resilient split BTF followups Follow-up to resilient split BTF series [1], - cleaning up libbpf relocation code (patch 1); - adding 'struct module' support for base BTF data (patch 2); - splitting out field iteration code into separate file (patch 3); - sharing libbpf relocation code with the kernel (patch 4); - adding a kbuild --btf_features flag to generate distilled base BTF in the module-specific case where KBUILD_EXTMOD is true (patch 5); and - adding test coverage for module-based kfunc dtor (patch 6) Generation of distilled base BTF for modules requires the pahole patch at [2], but without it we just won't get distilled base BTF (and thus BTF relocation on module load) for bpf_testmod.ko. Changes since v1 [3]: - fixed line lengths and made comparison an explicit == 0 (Andrii, patch 1) - moved btf_iter.c changes to separate patch (Andrii, patch 3) - grouped common targets in kernel/bpf/Makefile (Andrii, patch 4) - updated bpf_testmod ctx alloc to use GFP_ATOMIC, and updated dtor selftest to use map-based dtor cleanup (Eduard, patch 6) [1] https://lore.kernel.org/bpf/20240613095014.357981-1-alan.maguire@oracle.com/ [2] https://lore.kernel.org/bpf/20240517102714.4072080-1-alan.maguire@oracle.com/ [3] https://lore.kernel.org/bpf/20240618162449.809994-1-alan.maguire@oracle.com/ ==================== Link: https://lore.kernel.org/r/20240620091733.1967885-1-alan.maguire@oracle.com 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 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.
