linux-next: manual merge of the tests tree

Hi Ananth,

Today's linux-next merge of the tests tree got a conflict in
lib/Kconfig.debug between commit 31a72bce0bd6f3e0114009288bccbc96376eeeca
("rcu: make rcutorture more vicious: reinstate boot-time testing") from
the sched tree and commit db00d6090740863199393461c8332812986ce4ad ("Move
rcutorture to tests/") from the tests tree.

Paul has added another CONFIG option related to the RCU tests. I fixed it
up, hopefully correctly.  Probably worth a look when I publish the tree.

Thanks Stephen! I'll take a look.

Its probably worth merging the tests/ tree in 2.6.27-rc1, given its been
in linux-next for over 3 months now.

Let me know, I will be happy to look it over.

							Thanx, Paul

Hi Ananth,

Today's linux-next merge of the tests tree got a conflicts in lib/Kconfig.debug.

You need to determine if this tree is ever going to be merged into Linus'
tree.  I am going to drop it until you decide.

Stephen,

I am at a loss to determine the same. Sam Ravnborg had taken on the task
to push it upstream and he has also tried a couple of times, without
success.

Sam?

Given the discussion, I am dropping the tests tree until something is
decided.  (in which case, I assume the tree will have its conflicts with
Linus' tree fixed up)

Agreed. We can revisit this when we have a proper framework to execute
small user space test programs.

Ananth - thanks for your effort but I will drop the tree too.

Hi Ananth,

Today's linux-next merge of the tests tree got a conflict in
lib/Kconfig.debug between commit 67182ae1c42206e516f7efb292b745e826497b24
("rcu, debug: detect stalled grace periods") from the sched tree and
commit 2b9b631dd2507b5480b752bcca946b9767b9bae1 ("Move rcutorture to
tests/") from the tests tree.

I sort of fixed it up.

Ananth, you should try to get the testing stuff into Linus' tree ...

Thanks Stephen.

We've tried multiple times already (last attempt was
http://marc.info/?l=linux-kernel&m=121727532926590&w=2).

Guess as Andrew said, this is way below in the priority scale. I am not
sure at this point if we should just let things be as they are if there
isn't much interest in merging it upstream.

linux-next: manual merge of the tests tree

[Stephen Rothwell]

Hi Ananth,

Today's linux-next merge of the tests tree got conflicts in
lib/Kconfig.debug against Linus' tree.

I have been carrying the fix to these conflicts for a while but no that
they are in Linus' tree, you should rebase/merge your tree against his
and carefully check/test the results.

My current fixup patch to your tests/Kconfig is below.  It may not be
complete.

Thanks Stephen!

Sam,

Can you please request Linus to pull the tests tree now that 2.6.27
window is open?

Thanks,

Hi Ananth,

Today's linux-next merge of the tests tree got a new conflict in
lib/Kconfig.debug between commit 1462a200057df08be12f3719e1f37adbd2c6e4d0
("Revert "prohibit rcutorture from being compiled into the kernel"") from
the sched tree and commit db00d6090740863199393461c8332812986ce4ad ("Move
rcutorture to tests/").

It is trivial and I did the obvious fixup and will carry that.
