[Bug 1772671] [NEW] Kernel produces empty lines in /proc/PID/status

[Hajo Locke]

Public bug reported:

Hello,

after running updates today to linux-
image-4.4.0-127-generic_4.4.0-127.153 and rebooting i noticed that iotop
is not working any more. Reason are empty lines in /proc/PID/status,
which confuse iotop (and me)

In new view there is an empy line between Seccomp and
Speculation_Store_Bypass:

####
Seccomp:        0

Speculation_Store_Bypass:       vulnerable
####
Speculation_Store_Bypass seems to be new in /proc/PID/status, may be a relation to spectre/meltdown patches.

iotop is first application which is failing here, but iam afraid of
more.

Thanks
