Example program:

For your example program, it would be useful to include the
system calls so it is easier to see what is going on, like:
#ifndef HAVE_NAME_TO_HANDLE
static inline int name_to_handle(const char *name, struct file_handle
*fh)
{
return syscall(338, name, fh);
}
static inline int open_by_handle(int dirfd, struct file_handle *fh,
int flags)
{
return syscall(339, dirfd, fh, flags);
}
#endif
int main(...)
{
ret = name_to_handle(argv[1], &fh);
:
dirfd = open("/", O_RDONLY|O_DIRECTORY);
fd = open_by_handle(dirfd, &fh, O_RDONLY);
:
:
}
