Problem
========
commit 658eb5ab91 ("delayacct: add delay max to record delay peak")
- adding more fields
commit f65c64f311 ("delayacct: add delay min to record delay peak")
- adding more fields
commit b016d08737 ("taskstats: modify taskstats version")
- version bump to 15
Since version 15 (TASKSTATS_VERSION=15) the new layout of the structure
adds fields in the middle of the structure, rendering all old software
incompatible with newer kernels and software compiled against the new
kernel headers incompatible with older kernels.
Solution
=========
move delay max and delay min to the end of taskstat, and bump
the version to 16 after the change
