After commit 21175ca434 ("ext4: make prefetch_block_bitmaps default"),
we enable 'prefetch_block_bitmaps' by default, but this is not shown in
the '/proc/fs/ext4/sdx/options' procfs interface.
This makes it impossible to distinguish whether the feature is enabled by
default or not, so 'prefetch_block_bitmaps' is shown in the 'options'
procfs interface when prefetch_block_bitmaps is enabled by default.
This makes it easy to notice changes to the default mount options between
versions through the '/proc/fs/ext4/sdx/options' procfs interface.

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 reStructuredText 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.
