Linux kernel source tree
6c1b8cb6a7
Add a new map test, map_percpu_stats.c, which is checking the correctness of
map's percpu elements counters. For supported maps the test upserts a number
of elements, checks the correctness of the counters, then deletes all the
elements and checks again that the counters sum drops down to zero.
The following map types are tested:
* BPF_MAP_TYPE_HASH, BPF_F_NO_PREALLOC
* BPF_MAP_TYPE_PERCPU_HASH, BPF_F_NO_PREALLOC
* BPF_MAP_TYPE_HASH,
* BPF_MAP_TYPE_PERCPU_HASH,
* BPF_MAP_TYPE_LRU_HASH
* BPF_MAP_TYPE_LRU_PERCPU_HASH
* BPF_MAP_TYPE_LRU_HASH, BPF_F_NO_COMMON_LRU
* BPF_MAP_TYPE_LRU_PERCPU_HASH, BPF_F_NO_COMMON_LRU
* BPF_MAP_TYPE_HASH_OF_MAPS

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.
