The latest linux kernels (2.6.25-rc4) continue supporting vmmon's reference to the kernel symbol 'init_mm', but after 2.6.25 (that is, starting with 2.6.26) this symbol will no longer be exported.

(The patch in 2.6.25 uses "EXPORT_UNUSED_SYMBOL(init_mm)", thereby requiring a kernel config option to actually export it.)

I believe Fedora's 2.6.25 kernels will start to support this, but the end is in sight for access to init_mm.....

Of course, I don't know the effort involved in "fixing" vmmon (or whether init_mm is actually used or just an artifact), but I'm hoping the changes will be available as the new kernels roll out.....
