delalloc space accounting problem.

It appears that delalloc lets me copy 50M of data onto a 30M filesystem; at least I never get ENOSPC back, although I wind up with several files that have 1M length but 0 blocks.

I've filed a bug in the kernel bug tracker, I think we could use a central place to track issues:

http://bugzilla.kernel.org/show_bug.cgi?id=9329

I'll try to find time to look into this unless someone knows offhand where the problem is...

Thanks,

(p.s. should I get ext[234] bug mail routed to this list, or would that be annoying?)

because new delalloc patch doesn't have reservation integrated. I'm going to implement this after data=order support.

thanks, Alex
