UBIFS: do not lie about used blocks (2edc2025) · Commits · 戴 / test

Do not force UBIFS return 0 used space when it is empty. It leads to a situation when creating any file immediately produces tens of used blocks, which looks very weird. It is better to be honest and say that some blocks are used even if the FS is empty. And ext2 does the same. Signed-off-by:
