It uses bio, each pagebuf does its I/O via 1 (or more if too large) bio 
structures, that is about it
for 2.5 specific changes. I have been working with Jens on this as XFS 
appears to be hitting
a couple of bugs in request merging - probably because it is the only 
serious user of larger
bio structs.

Because of this there is a good chance of crashes with this tree right 
now, it is strictly developer
only material at the moment.

The code base is 2.5.1-pre5 + another bio patch from Jens, the XFS in 
this tree is actually
about a week out of date, I will merge over relevant XFS changes at some 
point soon. The
same commands can be used with the 2.5 kernel, we do not plan on 
providing two different
sets.
