YAFFS derives its free space by counting the number of free "chunks" (pages) 
and subtracting a reserved space for garbage collection etc. It does not 
include partially used pages in the free space calculation since the partial 
pages are allocated and are thus in use.

Why woul you want to do that? THere is no guarantee that you can get the 
space in a partially used page since that page is allocated to a file.
