Hm, looking at the code - indeed, we do this with MDS too, here is the
relevant comment:
* We need to hack the return value for the free inode counts because
* the current EA code requires one filesystem block per inode with
EAs,
* so it is possible to run out of blocks before we run out of inodes.
*
* This can be removed when the ext3 EA code is fixed.
This is no longer totally true, and only true if you have very wide
striping that does not fit into reserved EA space in inode.
Is this under-reporting breaking anything for you, I wonder?
Bye,
Oleg
