I support merge, Linus seemed to support it with the caveat that he said 
he didn't personally see much discussion...

No comment other than I notice tytso's patches got dropped (at least 
once/twice?).  Maybe viro hasn't reviewed them?

IIRC viro had some objections to ACLs in general and how they might not 
necessarily actually improve security -- but I did not see detailed 
elaboration on this.

I dunno if this needs to be in the kernel...

Needs sysfs support or devmapperfs support... no need to add a bunch of 
ioctls that will go away eventually.

Rob - this URL doesn't seen to have anything directly to do with large 
page support.

Others-
Is this not already in the kernel?  I still want to actually see someone 
from Oracle actually say "I will use this" or "we find this useful".

[I cynically propose a sys_oracle and be done with it <g>]

IMO 2.7.x item...

why does this need to be the mainline kernel?  this is another type of 
thing that can live as a patch, IMO...

this is already merged, isn't it??

no comment, I've heard arguments that high-res timers would be useful, 
but haven't read the patch myself so won't comment...

Sounds like 2.7.x material, viro pointed out several problems ...

I would personally _love_ to see this merged, but I think it's 2.7.x 
material given the recent comments (unless they get fixed up)

needs more review... but hasn't some of this stuff already made it in?
(or am I thinking about fbdev...?)

Useful, but at the same time not many people will use this I think.  It 
may need to live as a patch for a while, if not for a long while...

The USAGI guys have been slowly splitting up their patches and 
submitting them... AFAIK DaveM is just waiting on more split-up IPv6 
patches from them...

at first glance this seems to have serious issues with being a black 
hole for overriding syscalls-type behavior...

most likely 2.7.x material

I dunno if people want to take the hit in the mainline kernel... Maybe 
this should be a CONFIG_xxx option, or live outside as a patch that 
enterprise customers integrate
