[Peter Jones]

As per Hongchao, this has been fixed by the landing of https://review.whamcloud.com/#/c/35318/

[Andreas Dilger]

At this point, it makes sense to just delete all uses of LMV_HASH_FLAG_DEAD rather than making the code conditional on the version.

Hongchao

Can you please investigate?

Thanks

Peter
