  18.      _d_e_v       The logical device number.

  23.      The _ssss_iiii_zzzz_eeee_6666_4444 entry point returns in _b_l_o_c_k_s the number of _NNNN_BBBB_PPPP_SSSS_CCCC_TTTT_RRRR-byte units
  24.      on a logical block device (partition), if successful.  If unsuccessful -1
  25.      is returned in _b_l_o_c_k_s.  _NNNN_BBBB_PPPP_SSSS_CCCC_TTTT_RRRR, defined in _pppp_aaaa_rrrr_aaaa_mmmm_...._hhhh, is the number of
  26.      bytes per logical disk sector.

  29.      On success, the _ssss_iiii_zzzz_eeee_6666_4444 routine should return 0; on failure, the return

  33.      This entry point is optional in all block device drivers, required only
  34.      when it is possible to have a device whose size _NNNN_BBBB_PPPP_SSSS_CCCC_TTTT_RRRR-byte units will
  35.      not fit into an _iiii_nnnn_tttt.
  36.  
  37.      _ssss_iiii_zzzz_eeee_6666_4444(D2) is called only when the device is open.

  40.      The _ssss_iiii_zzzz_eeee_6666_4444 routine has user context and can sleep.  However, it should be
  41.      careful not to spend much time sleeping, especially if the routine is
  42.      called when the logical device is not open.
