Sub-page block support is still unusable even with previous commits if
interlaced PLAIN pclusters exist. Such pclusters can be found if the
fragment feature is enabled.
This commit tries to handle "the head part" of interlaced PLAIN
pclusters first: it was once explained in commit fdffc091e6 ("erofs:
support interlaced uncompressed data for compressed files").
It uses a unique way for both shifted and interlaced PLAIN pclusters.
As an added bonus, PLAIN pclusters larger than the block size is also
supported now for the upcoming large lclusters.

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.
