    ext4: documentation fixes · 219db95b

    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    - Superblock struct was outdated, added the new fields which were part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.
