I don't have `apport-collect` on my nodes.
But I can confirm the problem exists.
```
# journalctl | grep -c 'testing the buffer'
2498
#
```

Title:
net/bpfilter: remove superfluous testing message
Status in linux package in Ubuntu:
Incomplete
Status in linux-hwe-5.0 package in Ubuntu:
Confirmed
Bug description:
[Impact]
A testing message was brought by 13d0f7b814d9 ("net/bpfilter: fix dprintf
usage for /dev/kmsg") but should've been deleted before patch submission.
Although it doesn't cause any harm to the code or functionality itself, it's
totally unpleasant to have it displayed on every loop iteration with no real
use case. Thus remove it unconditionally.
Upstream fix: 41c55ea6c2a7ca4c663eeec05bdf54f4e2419699
[Test Case]
Just check dmesg:
[ 10.635382] hv_utils: VSS: userspace daemon ver. 129 connected
[ 15.306015] bpfilter: Loaded bpfilter_umh pid 1036
[ 15.306280] Started bpfilter
[ 15.306283] testing the buffer
[ 15.306458] testing the buffer
[ 15.306880] testing the buffer
[ 15.318003] testing the buffer
[ 15.318057] testing the buffer
[ 15.318814] testing the buffer
[ 15.442147] testing the buffer
[ 15.479556] testing the buffer
[ 15.479572] testing the buffer
[Regression Potential]
Very low. The fix is a one line upstream patch that removes one
printf.
