/*

 * 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.
