See http://www.infradead.org/rpr.html Call blk_validate_limits on the queue limits used for zone append splitting so that calculated values get filled in and any stacking conflicts get cought. Without this there isn't a max_zone_append_sectors limits as of commit 559218d43ec9 ("block: pre-calculate max_zone_append_sectors").
