Recent change [0] resulted in a "BUG: using __this_cpu_read() in preemptible" splat [1]. PREEMPT kernels have additional requirements on what can and can not run with/without preemption enabled. Expose those constrains in the debug kernels. 0: https://lore.kernel.org/netdev/20250314120048.12569-2-justin.iurman@uliege.be/ 1: https://lore.kernel.org/netdev/20250402094458.006ba2a7@kernel.org/T/#mbf72641e9d7d274daee9003ef5edf6833201f1bc Signed-off-by: Stanislav Fomichev <sdf@fomichev.me> Reviewed-by: Simon Horman <horms@kernel.org> Acked-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Link: https://patch.msgid.link/20250402172305.1775226-1-sdf@fomichev.me Signed-off-by: Jakub Kicinski <kuba@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.
