If this file is copied from a pre-existing file with double copyright,
and substantially borrows from that content rather than being fresh
material, then keeping double copyright is ideal.  If this is something
you mostly wrote yourself, and then just copied in boilerplate, then
it's simpler to just put one copyright line for yourself (in this case,
IBM); then later, if other contributors make contributions, a second
line can be added then (I tend to add Red Hat copyright whenever I touch
files, since I'm doing my work on Red Hat time).  I don't see it as a
show-stopper either way, because these days, git log is more reliable
for telling who contributed what portions of a file.
