Actually, only the sysop knows which is more important: doing the mount 
storm to respond to stat() or statfs(), or avoiding the storm.
      
Agreed. In our case, we have 'heavily discouraged' use of /net on our
big servers and we would prefer that statfs()/stat() waited for the
automount to complete.
    

Just to be absolutely clear.

The "browse" or "--ghost option isn't being used, in oder to avoid mount
storms, but we still see stat(2) and statfs(2) (et. al.) not wait for a
mount to complete.

Is that right?
Is anyone in a position to test a kernel patch?

  
I may be willing to try the patch, but first I need to see if I can recreate the problem reliably.  If not, there isn't much use.  I just know that on our "faster" servers, the programmers I work with have demonstrated the issue.  I will need their help.  I'll let know if I make head way.  Thanks,

P.S. Chris, can you reliably demonstrate the not waiting for the mount problem?
