c9294d1f06 Reorder metadata updating pattern in WT mode
There's a possibility that WT write is performed to dirty cache line (i.e. after
switching WB->WT without flush) and status bits change from dirty to clean. If
power failure occurs it might happen that recovery would ignore recent data from
cache and would assume that data is clean while backend storage data is out of
date.

0192ce23dd Reorder metadata updating patter in WB mode
In WB mode metadata should be updated only if the actuall data had been saved
on disk. Otherwise metadata might be flushed too early and consequently data
corruption might occur.
