Linux kernel source tree

It'll use tools/include copy of linux/fs.h to generate a table to be
used by tools, initially by the 'mount' and 'umount' beautifiers in
'perf trace', but that could also be used to translate from a string
constant to the integer value to be used in a eBPF or tracefs tracepoint
filter.
When used without any args it produces:
$ tools/perf/trace/beauty/mount_flags.sh
static const char *mount_flags[] = {
[1 ? (ilog2(1) + 1) : 0] = "RDONLY",
[2 ? (ilog2(2) + 1) : 0] = "NOSUID",
[4 ? (ilog2(4) + 1) : 0] = "NODEV",
[8 ? (ilog2(8) + 1) : 0] = "NOEXEC",
[16 ? (ilog2(16) + 1) : 0] = "SYNCHRONOUS",
[32 ? (ilog2(32) + 1) : 0] = "REMOUNT",
[64 ? (ilog2(64) + 1) : 0] = "MANDLOCK",
[128 ? (ilog2(128) + 1) : 0] = "DIRSYNC",
[1024 ? (ilog2(1024) + 1) : 0] = "NOATIME",
[2048 ? (ilog2(2048) + 1) : 0] = "NODIRATIME",

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.
