Unfortunately, it didn't attach. If you can inline the content of the
test code, that would be helpful.

I don't know what the function signature of file_op is. This is an
important detail!
I would expect:
p.map(partial(file_op,lineop=unity),input)
and:
p.map(lambda x:file_op(x,lineop=unity), input)
to be functionality equivalent.
However, I do not know, without seeing file_op, whether:
p.map(lambda x:file_op(x, lineop=unity), input)
versus:
p.map(lambda x:file_op(x, unity), input)
Depending on method signature, this might not be equivalent,
especially if file_op takes in multiple keyword arguments.
Also, I don't know what you mean by "works" vs. "doesn't work": those
are human expressions that are ambiguous enough that I only know
something is wrong, but I don't know what. :) Can you be more
specific? If you see error messages or stack traces, please post
them, as they are additional "signal" that may be helpful in figuring
out what's happening.
