Quota Hash Abstraction 2.6.0-test2

Hi Everyone!

Last time I posted the Quota Hash Abstraction for 2.4
somebody suggested doing it for 2.6, because it "might
be interesting", so I thought, give it a try, and here
it is ...

please, if somebody has any quota tests, which he/she
is willing to do on this code, or just want to do some
testing with this code, do it and send me the results ...

this patch requires the quota fix done by Jan Kara, 
otherwise quota would not work at all ... 

TIA,
Herbert

the quota fix was included in the next (test) release
so default quota will work again ...

the Quota Hash Abstraction is neither a (big) performance
gain nor a feature bonus for the end user ... it is more
an enhancement to the code itself, allowing to have more
than one quota hash for arbitrary purposes ...

I doubt, that this code will ever make it into mainline
without another 'good' reason to use it, but maybe the
--bind mount quota stuff would be such a reason, if the 
interest for such things will eventually grow ...

HTH,
Herbert

Thanks for the quick response, that was my prime concern. I expect to
need quota again in the near future.

Big help, I have never had a performance problem with the quota stuff
other than not performing at all ;-) Good to have the code handy though,
use often follows capability rather than drives it.
