Sorry, couldn't follow you.

The new (outside eba.c) calls to 'ubi_next_sqnum' are from
'ubi_write_fastmap' (called from the 'ubi_update_fastmap' interface,
implemented in fastmap.c) - during construction of VID headers of the
FM_SB and FM_FATA.

IMO this is reasonable.

Do you suggest to somehow use existing ubi_eba_write_xxx functions?
Or place the FM_SB/FM_DATA peb writing funtions into eba.c?

Regards,
Shmulik
