For the inode of which we have so many instances it is. Especially when
only one filesystem can make use of this new field.
Personally
I somewhat prefer what I did in
http://www.spinics.net/lists/linux-fsdevel/msg74927.html
where we don't introduce additional method but rather a table with field
offsets in superblock. If people agree with this, I can cook up a patch for
quota relatively quickly.
There's an even better way. We stopped calling the dquot_* functions
from generic code, so now the filesystem can simply pass in a pointer
to the dquot array.
