Subject: Re: [RFC PATCH 60/62] orangefs: make use of ->free_inode()

Hi Linus and Al...

I just wanted Al to know I tested his patch and acked it and that it
there would be
a conflict if our pagecache code got pulled... I wasn't suggesting that I
should get that one part of Al's patch pulled...

>> I can easily handle any trivial conflicts this causes...

Thanks :-)
