When INCOMPAT_BIG_PCLUSTER sb feature is enabled, legacy compress indexes will also have the same on-disk header compact indexes to keep per-file configurations instead of leaving it zeroed. If ADVISE_BIG_PCLUSTER is set for a file, CBLKCNT will be loaded for each pcluster in this file by parsing 1st non-head lcluster.

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.
