- * xbf_low is used by the allocator to activate the lowspace algorithm -
- * when free space is running low the extent allocator may choose to
- * allocate an extent from an AG without leaving sufficient space for
- * a btree split when inserting the new extent. In this case the allocator
- * will enable the lowspace algorithm which is supposed to allow further
- * allocations (such as btree splits and newroots) to allocate from
- * sequential AGs. In order to avoid locking AGs out of order the lowspace
- * algorithm will start searching for free space from AG 0. If the correct
- * transaction reservations have been made then this algorithm will eventually
- * find all the space it needs.
