PFA v3. Changes: fixed few typos in comments. BTW, reviewing this patch again I cannot understand why we verify link coherence only on leaf level but not for internal pages? I do not see any actual problems here. Corruption detection power of leftlink-rightlinks on internal pages is diminishingly small compared to leaf pages. But there seems to be no reason to exclude internal pages? Thanks! Best regards, Andrey Borodin.
