I am playing with mtdconcat in MTD (Memory Technology Device).

For example:
  mtdconcat must be called after initializing the lower device and
  partitions. So, the order of calling functions must be decided
  always.

Actuall, the functions in Linux kernel are called in a order. I want
to know how to specify these orders.

Sorry for short English. Thank you for your help.
