ia64: perfmon: add d_dname method
Switch ia64/perfmon to using the d_dname() instead of relying on __d_path() to prepend the name of the root dentry to the path. CC: Tony Luck <tony.luck@intel.com> CC: Fenghua Yu <fenghua.yu@intel.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
