Subject: Re: [f2fs-dev] [PATCH v2] f2fs: introduce blk_alloc_mode mount option

I agree with you. But still I think "fragment" mode should work even
in low free space conditions.
Otherwise, it will be seeking the free blocks again and again like a busy loop.
Or we can change the block allocation way into adaptive mode under low
free space even staying in "fragment" mode.

If we can handle this, we might use "fragment" mode for both
simulating after fragmentation and making the filesystem fragmented.
