I got nervous when I tried this on an -O bigalloc -C 65536 fs:

# echo foo > blah; du -hc blah; sync; du -hc blah

64K total

Seems that du should never report less than the cluster size, should it?

Yes, that seems like a bug.

And that made me wonder about ENOSPC handling - are we tracing
delalloc allocations correctly?

From running xfstest 204 on a similarly-created fs, it really seems
that we are not....

Ted, are you aware of those issues in bigalloc?

No, this is news to me.  I'll have to take a closer look at this;
thanks for bring this up.
