I thought that we can not reclaim the line pointers unless we remove the corresponding index entries as well. Isn't that the case ? If so, how would we reclaim the line pointers after the last used one ?
There might be index pointers to dead line pointers in the proposed truncation scheme, so those can't be reclaimed, but after the index pointers are removed and the line pointers are unused like they are today, they could be reclaimed.
