I'm going to do another round of tests and buildworld this afternoon to verify the diff and then I'm committing to head. This is a very large feature and fundamentally changes softupdates.

Has this been tested performance wise (I know it doesn't make logistical sense, but it does kind of seem to null and void the importance of geom with journaling, maybe...)? A quick update; I found a bug with snapshots that held up the commit. Hopefully I will be done with it tonight. About gjournal; there would be no reason to use the two together. There may be cases where each is faster. In fact it is very likely. pjd has said he thinks suj will simply replace gjournal. GEOM itself is no less important with suj in place as it of course fills many roles. Performance testing has been done. There is no regression in softdep performance with journaling disabled. With journaling enabled there are some cases that are slightly slower. It adds an extra ordered write so any time you modify the filesystem metadata and then require it to be synchronously written to disk you may wait for an extra transaction. There are ways to further improve the performance. In fact I did some experiments that showed dbench performance nearly identical to vanilla softdep if I can resolve one wait situation. Although this is not trivial it is possible. The CPU overhead ended up being surprisingly trivial in the cases I tested. Really the extra overhead is only when doing sync writes that allocate new blocks. I am eager to see wider coverage and hear feedback from more people.

THIS It's hard for me to talk about RAID and FreeBSD without getting into a long sermon, so I'll try to keep this short. RAID is about data integrity, not about mirror/stripe/parity algorithms. Those algorithms are just a small part of RAID, and are merely tools for achieving the goals of RAID. But RAID != algorithms. It's like how we use linked lists extensively within the kernel, but the kernel != linked lists. A well-designed software raid stack is going to be an engine that manages topology, executes and rolls back I/O transactions, and handles error recovery. On-disk metadata is again just an algorithm that is part of this whole picture, and should be modularized as such along with the transforms. And to be even more brief, the existing GEOM RAID modules are designed in completely the wrong direction from this. Caveat Emptor.

IPv6 was included in GENERIC. This is an issue for both IPv4 and
IPv6 people.

do additional step to enable it (ifconfig inet6 -ifdisabled in this

do rc.conf in advance.
do
do Why not? There is no reason you can't have ifconfig_* lines for
do interfaces that are not always configured, I do it all the time.
Because the interface identifier cannot always be known in advance.
For example, IPv6 tunnel server/client which accept an incoming
connection and establish a gif tunnel between the two create a lot of
gif interfaces on demand, and the created gif interfaces must be
ready for IPv6 without ifconfig -ifdisabled if the sysadmin wants
IPv6. The net/dtcp{,client} in the ports collection is one of the
typical applications. This situation is also common in a
linkup/linkdown scripts for PPP(IPV6CP). Having all possible
interface names in rc.conf is not practical even if the number of
interfaces is small. IPv6 people (including me) surely want a knob
for -ifdisabled on interfaces with no $ifconfig line in rc.conf if
an interface has the ifdisabled flag. Without it, such kind of
programs do not work.
Of course we can fix the programs to always use -ifdisabled, but the
ifdisabled flag should not become popular for users. I reluctantly
designed the ifdisabled flag only for IPv4 people who hate a
link-local addr, in order to make IPv6 enabled by default as much as
possible with minimal impact to them as well as IPv6 people. This is
*the reason* why I improved the ifdisabled flag and used it in the
rc.d scripts. This has no compatibility with other KAME-derived
implementation, and for IPv6 people it is nothing but an annoying
obstacle.
The ifdisabled flag never disables the IPv6 functionality, and it can
make various wired situations for IPv6 people because the
functionality is enabled but the communication including the critical
ones is disabled. It can be used only as a seatbelt for IPv4 people;
not as a generic way to disable IPv6 on an interface. My design was
discussed with ex-KAME members last year and we all agreed that the
ifdisabled flag should not be abused in a way other than that. You
can see the difference between disabling the functionality and
disabling the communication if you read sys/netinet6*.
Anyway, if we will go ahead with to use IPv6 please do ifconfig
inet6 -ifdisabled first or please always add the interface name to
rc.conf as the current implementation does, I will revert my changes
which added support of the ifdisabled flag into ifconfig before
BSDCan. This flag is just needed to solve the issues I explained in

removing the flag makes the world much simpler.

Throughout your post you are *theorizing* about what you *think* will

actually tested it.
BEFORE you make any changes to the existing code you need to do some
actual testing, publish your methods and results, make a persuasive
argument for your proposed changes, and let other people review your
work and have a chance to respond.
I feel that I have tried very hard to be patient here, and I continue to

However I think your current stance is unreasonable, and what you've

2. The case of people randomly creating tunnels on the command line is

what you are proposing (auto-magic configuration of link-local for
tunnels) is even what the majority of users want.
do IPv4 people hates that gif0 has an IPv6 link-local (and IPv6
do communication itself),

do People who don't want v6 at all compile it out of the kernel, and the
do whole problem goes away. The project made a decision a long time ago to
do ship with v6 in GENERIC, so this is not a new issue.
No, the auto link-local addr assignment was turned to off by default
some years ago for this reason. This was a secteam's decision after
IPv6 was included in GENERIC. This is an issue for both IPv4 and
IPv6 people.
LOL ... If what you're saying is accurate then you're actually trying
to subvert the defaults, not restore them. If the secteam decided that
link-local addresses should not be created by default then even if your
description of what the current code does is accurate, it is doing
exactly what it should be doing.
do and IPv6 people hates that it needs an
do additional step to enable it (ifconfig inet6 -ifdisabled in this
do case). gif (and other cloned interfaces) can be created by a program
do (a ppp script, for example), so we cannot prepare $ifconfig line in
do rc.conf in advance.
do
do Why not? There is no reason you can't have ifconfig_* lines for
do interfaces that are not always configured, I do it all the time.
Because the interface identifier cannot always be known in advance.
For example, IPv6 tunnel server/client which accept an incoming
connection and establish a gif tunnel between the two create a lot of
gif interfaces on demand, and the created gif interfaces must be
ready for IPv6 without ifconfig -ifdisabled if the sysadmin wants
IPv6. The net/dtcp{,client} in the ports collection is one of the
typical applications. This situation is also common in a
linkup/linkdown scripts for PPP(IPV6CP). Having all possible
interface names in rc.conf is not practical even if the number of
interfaces is small. IPv6 people (including me) surely want a knob
for -ifdisabled on interfaces with no $ifconfig line in rc.conf if
an interface has the ifdisabled flag. Without it, such kind of
programs do not work.
Please provide actual examples of what you're describing that I can set
up and test. Also, please explain why (if it is necessary at all) that
