Hello All,

I was intrigued by this slide show
http://wiki.lustre.org/images/1/1f/Lug_johann.pdf


I have a question on slide 5

Kernel patches needed
> Re-add journal callback support in jbd
> Jbd fixes & statistics
> scsi disk statistics
    – could be removed if blktrace enabled
> Export some symbols used by lustre
> API for setting block device read-only
> ...


What is the purpose of these extra kernel patches? I was under the
impression on Lustre patch for the kernel is needed for the MDS/OSS.
Where can I find a full list the patches I need to "enchance" our
OSS/MDS?

TIA
