[Pvfs2-developers] setuid bit support

What is the status of setuid bit support in PVFS these days?

super.c indicates that there is a "suid" mount option.  PVFS seems to 
accept this, but the option does not show up in the mount output once 
the file system is mounted.

With or without that mount option, any attempts to chmod with the setuid 
bit return EINVAL.  If kernel logging is turned on, this shows up in the 
kernel logs: "Attempting to set setuid bit (not supported); returning 
EINVAL."

I happen to be trying this on a 2.6.15.4 kernel with the trunk version 
of PVFS at the moment.

thanks!
