statfs hangs

[John Meyers]

Hi,
        I find that statfs hangs on locked up nfs directories.
I mount a remote nfs share .That machine goes down.Now when i access that 
share using statfs("/sharename"..) i get  hang .When i see the glibc 
sources i dont find where exactly is the statfs or statvfs located.

Also if statfs is called __statfs there is only one thing in the function 
in setting error number __set_errno (ENOSYS);. I am talking about the file 
sysdeps/generic/statfs.c in glibc.So what is happening exactly ?WHy is 
statfs locking up and where is the code for statfs.c which causes the 
hang.


Thank you
Meyers
