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.

If a BPF map is created over 2^32 the memlock value as displayed in JSON
format will be incorrect. Use atoll instead of atoi so that the correct
number is displayed.
```
$ bpftool map create /sys/fs/bpf/test_bpfmap type hash key 4 \
value 1024 entries 4194304 name test_bpfmap
$ bpftool map list
1: hash name test_bpfmap flags 0x0
key 4B value 1024B max_entries 4194304 memlock 4328521728B
$ sudo bpftool map list -j | jq .[].bytes_memlock
33554432
```
