[pnfs] pNFS 2.6.17

[Marc Eshel]

I just tried to run pNFS 2.6.17 and it did not work. Did any one got it to 
work with the file protocol? 
I tried mount and read, it did get the device list but it never requested 
the layout from the MDS it was just hang.

On another subject, just before moving to 2.6.17 I applied the 1MB 
read/write patch from Greg Banks at it seemed to work fine, so if know one 
objects I would like to apply it to 2.6.17. One problem that I saw testing 
with 1MB read size is that the client ignored the stripe unite that the 
MDS specified in the layout stripe unit and used the 1MB read size which 
is wrong.
