Previously, the specifier '%pD' is for printing dentry name of struct

As suggested by Linus [1]:

Citing is better looked when you shift right it by two white spaces.

A dentry has a parent, but at the same time, a dentry really does
inherently have "one name" (and given just the dentry pointers, you
can't show mount-related parenthood, so in many ways the "show just
one name" makes sense for "%pd" in ways it doesn't necessarily for
"%pD"). But while a dentry arguably has that "one primary component",
a _file_ is certainly not exclusively about that last component.

Hence change the behavior of '%pD' to print the full path of that file.

Precision is never going to be used with %p (or any of its kernel
extensions) if -Wformat is turned on.

Shouldn't be blank lines in the tag block. I have an impression that I have
commented on this already...

-last components.  %pD does the same thing for struct file.
+last components.  %pD prints full file path together with mount-related

I guess you may also convert double space to a single one.
