Linux 3.9 compat: vfs_getattr takes two arguments
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@3dadecce20603aa380023c65e6f55f108fd5e952 modified
vfs_getattr to take struct path * is taken as an argument instead.
