Introduces erofs compressed tail-packing inline support. This approach adds a new field called `h_idata_size' in the per-file compression header to indicate the encoded size of each tail-packing pcluster. At runtime, it will find the start logical offset of the tail pcluster when initializing per-inode zmap and record such extent (headlcn, idataoff) information to the in-memory inode. Therefore, follow-on requests can directly recognize if one pcluster is a tail-packing inline pcluster or not.

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.
