Comment 138 for bug 238208

Great work, thanks for your work!
Just to make a little report, this worked great on Debian Squeeze 2.6.32-5, but it doesn't build at all on Mandriva 2.6.33, whining about round_down and other functions not being defined. Adding an include linux/kernel.h or removing the kernel version check around the defines in compatibility.h only causes more errors.
