The log merging work deletes log trees items once their item roots are merged back into the fs root. Those deleted items could still have populated srch files that would be lost. We force rotation of the srch files in the items as they're reclaimed to turn them into rotated srch files that can be compacted. Signed-off-by: Zach Brown <zab@versity.com>
