That's for power management.

You should not be looking in there. You should be calling the mtd->read(),
mtd->write() and mtd->erase() functions. The latter is already permitted to
return immediately, calling a caller-provided callback later on completion.
The read function already suspends active erases to fulfil the read
request. You can easily make the write function do the same, on chips that
support it.
