Compatibility Lustre 2.15.3

[b-vm]

Uncommenting this was necessary to run make rpm for Lustre 2.15.3:

robinhood/src/common/lustre_tools.c

Lines 850 to 858 in 509584b

	/* A new LL_IOC_MDC_GETINFO has been defined since Lustre 2.12.4,
	* but it doesn't return a struct stat.
	* Use the old (compatible) ioctl() instead.
	*/
	#ifdef IOC_MDC_GETFILEINFO_OLD
	# define IOC_MDC_GETFILEINFO_V1 IOC_MDC_GETFILEINFO_OLD
	#else
	# define IOC_MDC_GETFILEINFO_V1 IOC_MDC_GETFILEINFO
	#endif

The error it caused before I uncommented that:

Uncommenting? Or commenting it out? Builds failed for me on 2.15.2 unless I commented out 854->858.
