It's a harmless complaint which can probably just be disabled. A short
while after you write to the flash, we decide to flush the write-buffer.
We prefer to do that by garbage-collection rather than just by padding
it out with zeroes.... but as the message says, there's nothing to GC
from. So we pad it instead.
