Miscalculation of lbas read/written

Line 1225 in de62589

a->pretty_value = fourtyeight * 65536LLU * 512LLU / 1000000LLU;

This line seems does lbas-read/written * 65536 * 512 (sectors) / 1000000 (mb). However on my various varieties of Samsung ssd this 65536 multiple is incorrect, it should actually just be * 512 / 1000000 to get mb. This means I'm having to put a *16 factor in to convert to bytes/sec

I noticed the same problem on my Samsun SSD (EVO 850). skdump returns 325214 TB written, which is nonsensical. So if I divide the reported LBA's written by 64k, is that the actual TBW value as recorded by my SSD?

Same issue with [Samsung SSD 860 EVO mSATA 500GB].
