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
internalpages?
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
thereseems to be no reason to exclude internal pages?
Thanks!
