What about the mntent related ones? Looking at mntent.h in
sysroot/usr/include/, it contains:

----

#ifndef _MNTENT_H_
#define _MNTENT_H_

#include <stdio.h>

#define MNTTYPE_IGNORE "ignore"

struct mntent
{
    char* mnt_fsname;
    char* mnt_dir;
    char* mnt_type;
    char* mnt_opts;
    int mnt_freq;
    int mnt_passno;
};


__BEGIN_DECLS


struct mntent* getmntent(FILE*);

__END_DECLS

#endif

----

So bits missing... The cgroup stuff I didn't look at. You are using the
32-bit variant as well, not the 64-bit one?
