            Bug ID: 60744
           Summary: waitid man page does not document the 5th argument
                    "struct rusage*"
           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: hannes-AXwPPc4i43WoxJ3sLSulrA@public.gmane.org
        Regression: No

I just spent 5 hours debugging my program and trying to figure out why the
kernel overwrote my stack. I had to read the source code to realize that the
real syscall took an additional 5th argument.

Wrong signature:
int waitid(idtype_t idtype, id_t id, siginfo_t *infop, int options);

Correct signature:
int waitid(idtype_t idtype, id_t id, siginfo_t *infop, int options, struct
rusage* rusage);

The kernel man pages should not assume that the user is using glibc, or at
least give enough information for developers to write their own, correct
wrappers.
