>Description:
nonspecific symbols min_offset and max_offset defined in uvm_map.h
may conflict with the names of unrelated simple variables declared
in other non-uvm source modules which indirectly include this file.
>How-To-Repeat:
compile any program source that includes <sys/vnode.h>
and declares variables named min_offset or max_offset.
>Fix:
suggested resolution: delete these symbol definitions in uvm_map.h,
modify the vm_map_min() and vm_map_max() macros to incorporate the
appropriate substitution directly, and alter all references to the
deleted symbols (27 total) in other modules to employ these macros.
