So I've picked that series up as this is still a useful addition.
Obviously too late for this merge window.

However, I stated multiple times that we're not going to add *xattrat()
variants that allow to set or get xattrs with AT_EMPTY_PATH on O_PATH
file descriptors. Not just because conceptually setting and getting
xattrs should be treated akin to read/write wrt to O_PATH but also
because it makes the concept of an O_PATH more and more meaningless if
we can do ever more things we it.

But it will also break assumptions of code that would be surprised if an
O_PATH fd suddenly can be used to set and get xattr. So I'll fix it up
so AT_EMPTY_PATH is handled to exclude O_PATH file descriptors.
