This is dangerous changes because this may this remove important sanity
check. It is false(not invalid) after few seconds after quotaon.
But later it can helps us to catch a lot of bugs. I have found chown bug
only because of this check.
I've attached a patch which add warning message, but after some thougths i
comes
in to idea to add force charging a reserved space in ->initialize() method
This allow us to preserve warning in claim_space, and helps us to handle
user misbehaviour. Will prepare patch in minute.
