Comment 34 for bug 1783591

@Christian: Something is weird with the stable-2.0 patch. It applies cleanly, but doesn't compile because it refers to LXC_PROC_PID_FD_LEN which doesn't exist and isn't added to the patch, so the code doesn't compile. I can fix the build by adding this line in utils.h:

#define LXC_PROC_PID_FD_LEN (6 + LXC_NUMSTRLEN64 + 4 + LXC_NUMSTRLEN64 + 1)
