This patch allows to run example given by open_by_handle_at(2): The following shell session demonstrates the use of these two programs: $ echo 'Can you please think about it?' > cecilia.txt $ ./t_name_to_handle_at cecilia.txt > fh $ ./t_open_by_handle_at < fh open_by_handle_at: Operation not permitted $ sudo ./t_open_by_handle_at < fh # Need CAP_SYS_ADMIN Read 31 bytes $ rm cecilia.txt Now we delete and (quickly) re-create the file so that it has the same content and (by chance) the same inode.[...] $ stat --printf="%i\n" cecilia.txt # Display inode number 4072121 $ rm cecilia.txt $ echo 'Can you please think about it?' > cecilia.txt $ stat --printf="%i\n" cecilia.txt # Check inode number 4072121 $ sudo ./t_open_by_handle_at < fh open_by_handle_at: Stale NFS file handle See the man page for source code.
