I'm talking about drivers in the mainline kernel tree.
In some cases the driver author supports both 2.4 and 2.6 and prefers to
support them in one file. Sometimes he submits the latest version of his
driver to Marcelo or Linus.
If you remove the global function dummies, you force every driver
maintainer who works this way to add the function dummies to their
drivers.
Yes, there are many places where 2.4 and 2.6 are not source compatible
for good reasons. But if the effort for maintaining compatibility
between 2.4 and 2.6 in one area is as easy as keeping a header file with
some dummy funtions it's worth considering.
And keeping the compatibility stuff in one file instead of spreaded
through the kernel sources makes the cleanup to remove the last
occurences a few years from now easier.
