Subject: vfsmount

I am interested in getting the vfsmount structure of the mounted file
system from my module.
I used filp = get_empty_filp() (filp is file pointer)
function to create an empty file object (as this contains pointer to
vfsmount structure)
file object has a field f_vfsmnt which points to the vfsmount structure
i am storing this in my own my_vfsmnt structure of type vfsmount.
my_vfsmnt = filp->f_vfsmnt
but i am getting my_vfsmnt as NULL ??

is there any other way of getting the vfsmount structure ??
