   7 ; XXX - libpmem exports mmap/munmap/msync/mprotect functions
   8 ;
   9 ; This is a _temporary_ solution to make those function available for all
  10 ; the other PMDK libraries and to have only one instance of a file mapping
  11 ; list (owned by libpmem).  Otherwise, each library would have its own
  12 ; instance of the file mapping list, resulting in libpmem being not able
  13 ; to find a file handle associated with the mapping address passed to
  14 ; pmem_msync(), pmem_memcpy(), etc. causing those functions to fail.
  15 ;
  16 ; The proposed target solution would include:
  17 ; - implementation of pmem_mmap, pmem_unmap, pmem_msync and
  18 ;   pmem_mprotect functions in libpmem (pmem_unmap and pmem_msync are
  19 ;   already there);
  20 ; - making sure that all the PMDK libraries never call mmap, munmap,
  21 ;   msync and mprotect directly, but only through their libpmem counterparts;
  22 ; - new pmem_mmap() function must provide similar functionality to
  23 ;   mmap(), i.e. it must take 'offset' argument, but should not take
  24 ;   file descriptor argument.  Perhaps it could be an opaque handle
  25 ;   to the file, that is internally casted to a file descriptor
  26 ;   or a HANDLE, depending on the OS.
