I've been stress testing large folio splits using the new debugfs interface with a new fstests test [0], to make the debugfs interface more useful it helps to do bounds checks on input parameters so this fixes two issues found while doing automatic stress testing of the debugfs interface with found files. Provided there are no issues I think this should go in for v6.9-rc6. Also, *should* we strive to support splits for large folios to min order with say MADV_NOHUGEPAGE ?
