From: "Alex Shi (tencent)" <alexs@xxxxxxxxxx> We can put off the flush action util a merging is realy coming. That could reduce some unmerge page flushing. BTW, flushing only do at arm, mips and few other archs.
I'm no expert on that flushing, but I thought we would have to do the flushing before accessing page content -- before calculating the checksum etc.
Now you would only do it before the pages_identical() check, but not when calculating the checksum.
