This is because systemd is awesome and +fallocate()'s its log space and writes into it. Unfortunately we assume that +when we read in all the csums for an extent that they are sequential starting at +the bytenr we care about. This obviously isn't the case for prealloc extents, +where we could have written to the middle of the prealloc extent only, which +means the csum would be for the bytenr in the middle of our range and not the +front of our range. Fix this by offsetting the new bytenr we are logging to +based on the original bytenr the csum was for. With this patch I no longer see +the csum errors I was seeing.
