Leon Hwang says: ==================== bpf, xdp: Add tracepoint to xdp attaching failure This series introduces a new tracepoint in bpf_xdp_link_attach(). By this tracepoint, error message will be captured when error happens in dev_xdp_attach(), e.g. invalid attaching flags. v4 -> v5: * Initialise the extack variable. * Fix code style issue of variable declaration lines. v3 -> v4: * Fix selftest-crashed issue. ==================== Link: https://lore.kernel.org/r/20230801142621.7925-1-hffilwlqm@gmail.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 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.
