ext4: prohibit fstrim in norecovery mode [ Upstream commit 18915b5873f07e5030e6fb108a050fa7c71c59fb ] The ext4 fstrim implementation uses the block bitmaps to find free space that can be discarded. If we haven't replayed the journal, the bitmaps will be stale and we absolutely *cannot* use stale metadata to zap the underlying storage. Signed-off-by: Darrick J.
