In preparation for adding dynamic inode allocation, separate an inode zone information from the zonefs inode structure. The new data structure zonefs_zone is introduced to store in memory information about a zone that must be kept throughout the lifetime of the device mount. Linking between a zone file inode and its zone information is done by setting the inode i_private field to point to a struct zonefs_zone. Using the i_private pointer avoids the need for adding a pointer in struct zonefs_inode_info. Beside the vfs inode, this structure is reduced to a mutex and a write open counter. One struct zonefs_zone is created per file inode on mount. These structures are organized in an array using the new struct zonefs_zone_group data structure to represent zone groups. The zonefs_zone arrays are indexed per file number (the index of a struct zonefs_zone in its array directly gives the file number/name for that zone file inode).

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.
