Re: 2.6.16+reiser4+openvz patches = error.

Hi,

I've played around with OpenVZ on my workstation at work, and the 
compilation problem is because the OpenVZ patch adds an extra argument 
to generic_permission to accomodate the more complex permission handling 
it has to do (e.g. no process, regardless of the UID, from a virtual 
server instance is allowed access to files outside of it's root 
directory, virtual servers themselves can be given disk quotas, etc; I 
don't remember exactly what the extra field was for as it was several 
months ago that I poked at the code to get it to compile).  However, 
though I was able to get reiser4 to compile with the OpenVZ patches, the 
fixing I did only allowed it to compile.  Not knowing the full scope of 
the reiser4 code nor the OpenVZ changes and how they should interact, 
OpenVZ and reiser4 don't play nicely together with the compilation fixes 
I made--if the virtual server directories were on a reiser4 filesystem 
then starting a virtual server would cause the system to hang fairly 
quickly.  My over-simplified solution to that problem was to put the 
OpenVZ directories in a separate partition that utilizes one of the 
in-kernel-tree filesystems that are supported by the OpenVZ patches 
(like reiser3 and xfs).  If anyone is interested in my compile fixes, 
let me know and I can post them tomorrow when I'm in the office.
