426  * mtd_wunit_to_pairing_info - get pairing information of a wunit
428  * @wunit: write unit we are interested in
431  * Retrieve pairing information associated to the wunit.
435  * The notion of page is replaced by the term wunit (write-unit) to stay
438  * The @wunit argument can be extracted from an absolute offset using
440  * to @wunit.
443  * @wunit using the following loop:
451 int mtd_wunit_to_pairing_info(struct mtd_info *mtd, int wunit,
457 	if (wunit < 0 || wunit >= npairs)
461 		return master->pairing->get_info(master, wunit, info);
464 	info->pair = wunit;
471  * mtd_pairing_info_to_wunit - get wunit from pairing information
475  * Returns a positive number representing the wunit associated to the info
489  *	wunit = mtd_pairing_info_to_wunit(mtd, &info);
490  *	mtd_write(mtd, mtd_wunit_to_offset(mtd, blkoffs, wunit),
1648 	unsigned int wunit, oobavail;
