Hi, all

we got the same issue http://tracker.ceph.com/issues/16279

I think it is possible objiter->second->version == last_divergent_update?

If olog is [200'5 ~ 200'10, 202'11~ 202'20] with object A: [200'5, 200'8]
   log is [200'3 ~ 200'11], object A : [200'5, 200'8]

Then after merge log os [200'3 ~ 200'10, 202'11~202'20] with divergent entry:
object A: 200'5 and 200'8

first_divergent_update will be 200'5 and last_divergent_update will be
200'8 for object A. If can find it in current log, and the possible
version the object A is equal or greater than 200'8.  So I am not sure
it must be greater than last_divergent_update but may be equal?

Am I missing something else?
