Thanks for working on this, Murali.  I recently upgraded to the 32 bit 
version of that same Ubuntu kernel so I gave your patch a shot too.  I 
had to use the --disable-kernel-aio configure option, otherwise I got a 
lot of these errors when copying files onto the NFS mount:

file.c line 2611: pvfs2_file_aio_write_iovec: not implemented yet (aio 
with 13 segments)

Not sure if I got it right, but I used the attached patch to build with 
--disable-kernel-aio.

At this point I can definitely create, remove, read, and write files, 
but I don't think that rename ("mv") is working, though.
