This commit aims to fix the following issues in ext4 documentation: - Flexible block group docs said that the aim was to group block metadata together instead of block group metadata. - The documentation consistly uses "location" instead of "block number". It is easy to confuse location to be an absolute offset on disk. Added a line to clarify all location values are in terms of block numbers. - Dirent2 docs said that the rec_len field is shortened instead of the name_len field. - Typo in bg_checksum description. - Inode size is 160 bytes now, and hence i_extra_isize is now 32. - Cluster size formula was incorrect, it did not include the +10 to s_log_cluster_size value. - Typo: there were two s_wtime_hi in the superblock struct. - Superblock struct was outdated, added the new fields which were part of s_reserved earlier. - Multiple mount protection seems to be implemented in fs/ext4/mmp.c.

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.
