Hi,

I have a ext4 file system on 2.6.34 that shows 0 blocks available
in "df" (it's nearly full but never got a ENOSPC). 

But when I delete a couple of files it still shows 0 blocks.
And I can actually create small files without problem, so clearly
there is at least some space available.

So is df reporting not accurate?

Thanks,
-Andi
