Subject: [GIT PULL] Btrfs fix for 6.4-rc8

Hi,

one more regression fix for an assertion failure that uncovered a nasty
problem with stripe calculations. This is caused by a u32 overflow when
there are enough devices. The fstests require 6 so this hasn't been
caught, I was able to hit it with 8.

The fix is minimal and only adds u64 casts, we'll clean that up later. I
did various additional tests to be sure. Please pull, thanks.
