One last question before I spin out v9.. the dma_mask code
is a bit confusing to me, so I want to make sure... the code is
> if (limit + tbl->it_offset > mask) {
> limit = mask - tbl->it_offset + 1;
> /* If we're constrained on address range, first try
> * at the masked hint to avoid O(n) search complexity,
> * but on second pass, start at 0 in pool 0.
> */
> if ((start & mask) >= limit || pass > 0) {
> spin_unlock(&(pool->lock));
> pool = &(tbl->pools[0]);
> spin_lock(&(pool->lock));
> start = pool->start;
So here I would need to mark need_flush to true, right?
