Won't that increase task_struct (16 bytes on 64-bit) unnecessarily?
The function pointers are common to all virtual machines.
well, this function pointer could then be reused by other virtual
machines as well, couldnt it?
I don't get this. If we add a couple of members to task_struct, it
can't be reused. The values will be the same across all tasks, but
the memory will be gone (including tasks which aren't virtual
machines).
i mean, the function pointer is set by KVM, but it could be set to a
different value by other hypervisors.
What other hypervisors? ;-)
Oh, if Rusty wants it for lguest I can put a pointer or a chain into
task_struct. But I doubt it -- with paravirtualization there are no
costly new registers to swap.
but ... no strong feelings either way, your patch is certainly fine.
