[pve-devel] [PATCH ksm-control-daemon] ksmtuned: fix large number processing

[Stefan Lendl <s.lendl@proxmox.com>]

awk internally uses float for every calculation, printing a large float
with awk results in 1.233e+09 format which causes the script to fail afterwards.
Instead I am printing the float without decimals.
