typical pfifo_fast qdiscs.
tcp_limit_output_bytes limits the number of bytes on qdisc
or device to reduce artificial RTT/cwnd and reduce bufferbloat.
Note: For GSO/TSO enabled flows, we try to have at least two
packets in flight. Reducing tcp_limit_output_bytes might also
reduce the size of individual GSO packet (64KB being the max)

kptr_restrict:
This toggle indicates whether restrictions are placed on
exposing kernel addresses via /proc and other interfaces. When
kptr_restrict is set to (0), there are no restrictions. When
kptr_restrict is set to (1), the default, kernel pointers
printed using the %pK format specifier will be replaced with 0's

exposing kernel addresses via /proc and other interfaces.
When kptr_restrict is set to (0), the default, there are no restrictions.
When kptr_restrict is set to (1), kernel pointers printed using the %pK
format specifier will be replaced with 0's unless the user has CAP_SYSLOG
and effective user and group ids are equal to the real ids. This is
because %pK checks are done at read() time rather than open() time, so
if permissions are elevated between the open() and the read() (e.g via
a setuid binary) then %pK will not leak kernel pointers to unprivileged
users. Note, this is a temporary solution only. The correct long-term
solution is to do the permission checks at open() time. Consider removing
world read permissions from files that use %pK, and using dmesg_restrict
to protect against uses of %pK in dmesg(8) if leaking kernel pointer
values to unprivileged users is a concern.
When kptr_restrict is set to (2), kernel pointers printed using
%pK will be replaced with 0's regardless of privileges.
