Linux kernel version 5.10 - we need changes

[VirtualBarista]

Linux kernel 5.10 won't work with the latest virtualbox 6.1.16, under Fedora 32/33.

/tmp/vbox.0/r0drv/linux/memobj-r0drv-linux.c: In function ‘rtR0MemObjLinuxVMap’: /tmp/vbox.0/r0drv/linux/memobj-r0drv-linux.c:560:34: error: implicit declaration of function ‘alloc_vm_area’ [-Werror=implicit-function-declaration]

560 | pMemLnx->pArea = alloc_vm_area(pMemLnx->Core.cb, papPtes); /* Note! pArea->nr_pages is not set. */

./tools/objtool/objtool orc generate --module --no-fp --retpoline --uaccess /tmp/vbox.0/SUPDrvTracer.o

Thank you.

PS: It seems like a common occurrence, first a new kernel is released, packaged and distributed to update repos, we update and discover that its not working, then wait 3-4 months for a new virtualbox. Maybe it would be possible to test future kernels earlier?

Looks like a duplicate of https://www.virtualbox.org/ticket/20055 .

@VirtualBarista: I have the same problem and I would appreciate your suggestion very much.
