I saw this subject line fly by and had the same thought, but now that I
come to read it there is a significant difference.

This is not "move cxl headers to new linux/cxl/ directory" this is
"rename existing cxl headers in include/linux/ to include/linux/cxl/".

Compare that to the proposal to move all drivers/cxl/*.h headers to
include/linux/.

Now, I do not think it makes sense to place these cross-driver cxl headers under
include/linux/cxl/, just place them under include/cxl/.

However, I do not understand the motivation. It's not like a new header
is being added and that is the final straw that merits moving the
existing headers. Most include/$subsys/ directories have more than 2
header files.

So what is the pain motivating this move?
