As described in Kconfig, the last compressed pack should be cached for further reading for either `EROFS_FS_ZIP_CACHE_UNIPOLAR' or `EROFS_FS_ZIP_CACHE_BIPOLAR' by design. However, there is a bug in z_erofs_do_read_page, it will switch `initial' to `false' at the very beginning before it decides to cache the last compressed pack. caching strategy should work properly after appling this patch.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
