Taking a quick look overall I see no issues with this series. Overall
it seems straight forward.

On the nit side I expect saying const struct path * in the functions
that now take a struct path would be useful.

I suspect it would also be useful to say
const struct path *path;
path = &file->f_path;

In the one part of the code where you do that. Instead of copying the
path out of the struct file.

Overall I expect that will keep down bugs at no reduction in usability.
Just a statement that the struct path won't change when it is passed
to various functions.
