Xu Kuohai says: ==================== Add kernel symbol for struct_ops trampoline. Without kernel symbol for struct_ops trampoline, the unwinder may produce unexpected stacktraces. For example, the x86 ORC and FP unwinder stops stacktrace on a struct_ops trampoline address since there is no kernel symbol for the address. v4: - Add a separate cleanup patch to remove unused member rcu from bpf_struct_ops_map (patch 1) - Use funcs_cnt instead of btf_type_vlen(vt) for links memory calculation in .map_mem_usage (patch 2) - Include ksyms[] memory in map_mem_usage (patch 3) - Various fixes in patch 3 (Thanks to Martin) v3: https://lore.kernel.org/bpf/20241111121641.2679885-1-xukuohai@huaweicloud.com/ - Add a separate cleanup patch to replace links_cnt with funcs_cnt - Allocate ksyms on-demand in update_elem() to stay with the links allocation way - Set ksym name to prog__<struct_ops_name>_<member_name> v2: https://lore.kernel.org/bpf/20241101111948.1570547-1-xukuohai@huaweicloud.com/ - Refine the commit message for clarity and fix a test bot warning v1: https://lore.kernel.org/bpf/20241030111533.907289-1-xukuohai@huaweicloud.com/ ==================== Reviewed-by: Martin KaFai Lau <martin.lau@kernel.org> Link: https://lore.kernel.org/r/20241112145849.3436772-1-xukuohai@huaweicloud.com Signed-off-by: Alexei Starovoitov <ast@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.
