Sounds likes we are trying to do a 64 bit division since timespec_to_ns()
returns a 64 bit value.

Here's a compile tested patch to fix the problem


It doesn't apply
cat patches/tsacct1.patch | patch -p1 --dry-run
patching file kernel/tsacct.c
Hunk #1 FAILED at 36.
1 out of 1 hunk FAILED -- saving rejects to file kernel/tsacct.c.rej

Andrew's csa-basic-accounting-over-taskstats-fix.patch fix compilation problem.
