[Pvfs2-users] latest CVS and linux kernel 2.6.26

[Ryuta Suzuki]

Hi Sumit, Phil,

I found what really screws up. I re-examined my build script, and sure 
enough, --enable-threaded-kmod-helper was there.
Removing this configuration option and rebuilding, pvfs2-client and 
mount work fine.

I understand that --enable-threaded-kmod-helper is experimental, yet.
I don't know why I put that configuration option to begin with, but at 
least we seem to find what caused the problem.

Thank you for your help.
