/**
* DOC: vma offset manager
*
* The vma-manager is responsible to map arbitrary driver-dependent memory
* regions into the linear user address-space. It provides offsets to the
* caller which can then be used on the address_space of the drm-device. It
* takes care to not overlap regions, size them appropriately and to not
* confuse mm-core by inconsistent fake vm_pgoff fields.
* Drivers shouldn't use this for object placement in VMEM. This manager should
* only be used to manage mappings into linear user-space VMs.
*
* We use drm_mm as backend to manage object allocations. But it is highly
* optimized for alloc/free calls, not lookups. Hence, we use an rb-tree to
* speed up offset lookups.
*
* You must not use multiple offset managers on a single address_space.
* Otherwise, mm-core will be unable to tear down memory mappings as the VM will
* no longer be linear. Please use VM_NONLINEAR in that case and implement your
* own offset managers.
*
* This offset manager works on page-based addresses. That is, every argument
* and return code (with the exception of drm_vma_node_offset_addr()) is given
* in number of pages, not number of bytes. That means, object sizes and offsets
* must always be page-aligned (as usual).
* If you want to get a valid byte-based user-space address for a given offset,
* please see drm_vma_node_offset_addr().
*
* Additionally to offset management, the vma offset manager also handles access
* management. For every open-file context that is allowed to access a given
* node, you must call drm_vma_node_allow(). Otherwise, an mmap() call on this
* open-file with the offset of the node will fail with -EACCES. To revoke
* access again, use drm_vma_node_revoke(). However, the caller is responsible
* for destroying already existing mappings, if required.

* Initialize a new offset-manager. The offset and area size available for the

*
