Jiri Olsa says: ==================== hi, Martynas reported kprobe _multi link does not resolve symbols from kernel modules, which attach by address works. In addition while fixing that I realized we do not take module reference if the module has kprobe_multi link on top of it and can be removed. There's mo crash related to this, it will silently disappear from ftrace tables, while kprobe_multi link stays up with no data. This patchset has fixes for both issues. v3 changes: - reorder fields in struct bpf_kprobe_multi_link [Andrii] - added ack [Andrii] v2 changes: - added acks (Song) - added comment to kallsyms_callback (Song) - change module_callback realloc logic (Andrii) - get rid of macros in tests (Andrii) thanks, jirka ==================== 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 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.
