Hi Bart,

I noticed that this static_assert fails when PAGE_SIZE is defined to
a value other than 4096.
I have to admit to being unfamiliar with f2fs. Is this an on-disk
data structure? If so, does it mean that non-4K page size kernels
are unable to mount f2fs file systems if the f2fs-tools were not
built with a matching PAGE_SIZE define?
In any event, maybe s/4096/PAGE_SIZE/g above is the correct fix
for now?
Peter
