Linux 3.9 compat: vfs_getattr takes two arguments

Browse Source 
The function prototype of vfs_getattr previoulsy took struct vfsmount *
and struct dentry * as arguments. These would always be defined together
in a struct path *.

torvalds/linux@3dadecce20 modified
vfs_getattr to take struct path * is taken as an argument instead.
