IMPLEMENTATION NOTES
It is the caller’s responsibility to obtain a lock on the map using vm_map_lock(9) before calling this function. This routine may call pmap_growkernel(9) to grow the kernel’s address space, if and only if the mapping is being made within the kernel address space, and if insufficient space remains in the kernel_map.
RETURN VALUES
The vm_map_findspace function returns the value 0 if successful, and *addr will contain the first virtual address in the found region; otherwise, the value 1 is returned.
