Re: [PATCH net] selftests/net: test network sysctl extremes

[Sahaj Chaudhari]

Thanks for the review. All three findings are valid.

1. [Medium] nf_hooks_lwtunnel cannot be disabled once enabled, so
   restoring the original value after a probe failed in --all mode.
   v2 drops --all and the full /proc/sys/net scan, and documents that
   only per-netns, restorable sysctls belong in the list.

2. [Medium] The rounding problem applied to sysctls that only --all
   reached (ms/jiffies conversions). The four remaining sysctls do not
   round, so find_bound() is not affected for them.

3. [Low] check_kernel_log() now ignores /dev/kmsg records whose facility
   is not LOG_KERN.
