Subject: fs/affs: bugfix: write files greater than page size on OFS
Previous AFFS patch fixed OFS write operations but unveiled another bug:
files greater than 4KB are being created with a wrong size resulting in
errors like the following:
dd if=/dev/zero of=file bs=4097 count=1
cp file /mnt/affs/
cp: error writing '/mnt/affs/file': Bad address
