Thanks to the excellent detective work and patch written by
Wolfram Sang, we have a fix for along standing issue in IDE.
The procfs directory for devices underneath an IDE controller
instance is not created before we try to makes nodes in that
directory.
The problem doesn't happen if, for example, you build everything
IDE statically into your kernel. This is because the individual
host controller drivers initialize first and probe the IDE
controllers. But the CDROM, disk, et al. driver's haven't
setup yet. They do so later, and at that point is when the
nodes in the procfs directory get created. And this works in
this case because the procfs directory is setup by the time
those device type drivers initialize.
But if we register an IDE controller device after the CDROM,
disk, et al. IDE modules have setup, we hit the problem.
Please pull, thanks a lot!
