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.

KASAN's quarantine might save its metadata inside freed objects. As this happens after the memory is zeroed by the slab allocator when init_on_free is enabled, the memory coming out of quarantine is not properly zeroed. This causes lib/test_meminit.c tests to fail with Generic KASAN. Zero the metadata when the object is removed from quarantine.
