uma_zone_reserve()), messages like the following appear on the console:
"Freed UMA keg (Test zone) was not empty (0 items). Lost 528 pages of
memory."
When keg_drain_domain() is draining the zone, it tries to keep the number
of items specified in the reservation. However, when we are destroying the
UMA zone, we do not need to keep those items. Therefore, when destroying a
non-secondary and non-cache zone, we should reset the keg reservation to 0
prior to draining the zone.

This in particular unbreaks rtkit.
The limitation was a leftover of previous state, to quote a
comment:
/*
* Though lwpid is unique, only current process is supported
* since there is no efficient way to look up a LWP yet.
*/
Long since then a global tid hash was introduced to remedy
the problem.
Permission checks still apply.

Memory savings fluctuate a lot, one sample result is buildworld on zfs
saving ~180MB RAM in reduced page count associated with zio caches.

Perhaps it made sense in 1998 (r32836), but now it feels a bit out of
place. We tend to avoid documenting non-essential ports variables in
the manual page (we try to document them in the Porter's Handbook instead).

In r367327 generic_bs_sr_<n> were derived from mips. Given we are calling
generic_bs_w_<n> and no write directly, we do not have to do the address
calculations ourselves as eneric_bs_w_<n> will do a str val [bsh, offset].
All we actually have to do is increment offset.

There are workloads with very bursty tid allocation and since unr tries very
hard to have small-sized bitmaps it keeps reallocating memory. Just doing
buildkernel gives almost 150k calls to free coming from unr.
This also gets rid of the hack which tried to postpone TID reuse.

The HPT is always stored in big-endian, as it is accessed directly by the
hardware as well as the kernel. As such, it is necessary to convert values
to and from native endian when running on LE.
Some unconverted accesses snuck in accidentally with r367417.
Apply the appropriate conversions to fix boot hanging on powerpc64le.

Currently there is no locking done to protect this structure. It is
likely okay due to the low-volume nature of IGMP, but allows for
the possibility of underflow. This appears to be one of the only
holdouts of the conversion to counter(9) which was done for most
protocol stat structures around 2013.
This also updates the visibility of this stats structure so that it can
be consumed from elsewhere in the kernel, consistent with the vast
majority of VNET_PCPUSTAT structures.

The goal of the fib support is to provide multiple independent
routing tables, isolated from each other.
net.add_addr_allfibs default tries to shift gears in the opposite
direction, unconditionally inserting all addresses to all of the fibs.
There are use cases when this is necessary, however this is not a
default expected behaviour, especially compared to other implementations.
Provide WARNING message for the setups with multiple fibs to notify
potential users of the feature.

- map those IPv4 / IPv6 socket options which exist in FreeBSD
+ most of them visually verified to have the same type/layout of arguments
+ not tested with linux programs to behave as intended
- be more human readable for known options which are not handled
- be more verbose for unhandled socket message flags we know about
- print the jail ID in linux_msg if run in a jail
- add possibility to print debug message about known missing parts only once
- add multiple levels of sysctl linux.debug:
1: print debug messages, tell about unimplemented stuff (only once)
2: like 1, but also print messages about implemented but not tested
stuff (only once)
3+: like 2, but no rate limiting of messages
- increase default linux debug level from 1 to 3
We are a lot more verbose in as we need to be (e.g. some of the IP socket
options which are the same, and share the same memory layout, and are
believed to work). The reason is that we have no good testsuite to test those
linux-bits. The LTP or other test suites like the python one, are not fully
up to the task we need. As such the excessive messages about emulated but not
tested socket options.
IMO any MFC (possible, but most probably not by me) should set the default
debug level to 1.
