Bug / missing feature workarounds:
REREAD - for RHEL3
LSBLK_NO_TYPE - SLES11.3 has not lsblk disk TYPE option
Options which should always but switched on:
SMALLMEM - removes huge memory, dirty, whritebak, mapped, slab, pagethreads as not in older kernels
PRE_KERNEL_2_6_18 1 kernel levels before removed the following to the disk stats
