Some of the tests do mount/umount dance when switching netns.
It is error-prone like
https://lore.kernel.org/bpf/20221123200829.2226254-1-sdf@xxxxxxxxxx/
Another issue is, there are many left over after running some of the
tests:
#> mount | egrep sysfs | wc -l
19
Instead of further debugging this dance, this set is to avoid the needs
to
do this remounting altogether. It will then allow those tests to be run
in parallel again.
Looks great, thank you for taking care of this! Since I'm partly to
blame for the mess, took a quick look at the series:
