Similar to the handling in the functions __register_btf_kfunc_id_set() and register_btf_id_dtor_kfuncs(), this patch uses the newly added helper check_btf_kconfigs() to handle module with its btf section stripped. While at it, the patch also adds the missed IS_ERR() check to fix the commitf6be98d199("bpf, net: switch to dynamic registration") Fixes:f6be98d199("bpf, net: switch to dynamic registration") Signed-off-by: Geliang Tang <tanggeliang@kylinos.cn> Link: https://lore.kernel.org/r/69082b9835463fe36f9e354bddf2d0a97df39c2b.1707373307.git.tanggeliang@kylinos.cn Signed-off-by: Martin KaFai Lau <martin.lau@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.
