2    Linus and the other developers sometimes change function or
3    structure names in development kernels; this is not done just to
4    keep everyone on their toes: it reflects a fundamental change
5    (eg. can no longer be called with interrupts on, or does extra
6    checks, or doesn't do checks which were caught before).  Usually
7    this is accompanied by a fairly complete note to the linux-kernel
8    mailing list; search the archive.  Simply doing a global replace
9    on the file usually makes things <span class="emphasis"><em>worse</em></span>.
