man (2) mmap says:
MAP_ANON Map anonymous memory not associated with any specific file.
The file descriptor used for creating MAP_ANON regions is
used only for naming, and may be specified as -1 if no name
is associated with the region.
But the ERRORS section of the same man page and the code in
sys/uvm/uvm_mmap.c suggest that the file descriptor must be -1 when
using MAP_ANON. Has this feature (creating a MAP_ANON region with an fd
used only for naming) been removed or has it not been implemented yet?
Or am I just confused?
