Core API Documentation
======================
This is the beginning of a manual for core kernel APIs. The conversion
(and writing!) of documents for this manual is much appreciated!
Core utilities
==============
This section has general and "core core" documentation. The first is a
massive grab-bag of kerneldoc info left over from the docbook days; it
should really be broken up someday when somebody finds the energy to do
it.
.. toctree::
:maxdepth: 1
kernel-api
workqueue
watch_queue
printk-basics
printk-formats
printk-index
symbol-namespaces
asm-annotations
real-time/index
Data structures and low-level utilities
=======================================
Library functionality that is used throughout the kernel.
.. toctree::
:maxdepth: 1
kobject
kref
cleanup
assoc_array
folio_queue
xarray
maple_tree
idr
circular-buffers
rbtree
generic-radix-tree
packing
this_cpu_ops
timekeeping
errseq
wrappers/atomic_t
wrappers/atomic_bitops
floating-point
union_find
min_heap
parser
list
Low level entry and exit
========================
.. toctree::
:maxdepth: 1
entry
Concurrency primitives
======================
How Linux keeps everything from happening at the same time. See
Documentation/locking/index.rst for more related documentation.
.. toctree::
:maxdepth: 1
refcount-vs-atomic
irq/index
local_ops
padata

Low-level hardware management
=============================
Cache management, managing CPU hotplug, etc.
.. toctree::
:maxdepth: 1
cachetlb
cpu_hotplug
memory-hotplug
genericirq
protection-keys
Memory management
=================
How to allocate and use memory in the kernel. Note that there is a lot
more memory-management documentation in Documentation/mm/index.rst.

Interfaces for kernel debugging
===============================

Everything else
