Some comments haven't been useful anymore since the code updated.
Let's drop them instead.

/*
* Logical to physical block mapping
*
* Different with other file systems, it is used for 2 access modes:
*
* 1) RAW access mode:
*
* Users pass a valid (m_lblk, m_lofs -- usually 0) pair,
* and get the valid m_pblk, m_pofs and the longest m_len(in bytes).
*
* Note that m_lblk in the RAW access mode refers to the number of
* the compressed ondisk block rather than the uncompressed
* in-memory block for the compressed file.
*
* m_pofs equals to m_lofs except for the inline data page.
*
* 2) Normal access mode:
*
* If the inode is not compressed, it has no difference with
* the RAW access mode. However, if the inode is compressed,
* users should pass a valid (m_lblk, m_lofs) pair, and get
* the needed m_pblk, m_pofs, m_len to get the compressed data
* and the updated m_lblk, m_lofs which indicates the start
* of the corresponding uncompressed data in the file.
