            Bug ID: 97051
           Summary: get_mempolicy(2) inconsistent with numaif.h
           Product: Documentation
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: man-pages
          Assignee: documentation_man-pages-ztI5WcYan/vQLgFONoPN62D2FQJk+8+b@public.gmane.org
          Reporter: nyh-TS7m/3hpY0sOpacJJkBjfT4kX+cae0hd@public.gmane.org
        Regression: No

get_mempolicy(2)'s synopsis is:

       #include <numaif.h>

       int get_mempolicy(int *mode, unsigned long *nodemask,
                         unsigned long maxnode, unsigned long addr,
                         unsigned long flags);

However, the actual prototype in numif.h (and implementation in numactl's
syscall.c) is subtly different:

       long get_mempolicy(int *policy, const unsigned long *nmask,
                        unsigned long maxnode, void *addr, int flags);

The funny thing is, that prototype is isn't quite right either - it pretends
nmask is a const pointer, but it most definitely isn't, and the data pointed by
it get written to. But that isn't a man-page bug.
