Hi all,

Today's tree will not build for powerpc allyesconfig, sparc(32) defconfig and probably some other configurations. I just ran out of time trying to fix all the errors. :-(

New trees:
iommu
watchdog
proc

Dropped trees:
tests (because its future is in doubt and it has conflicts) hid (too many conflicts for me to fix today) v4l-dvb (the tree is a mess)
sparseirq (too many conflicts for me to fix today) scsi-post-merge (appears to be superceded)
bdev (too many conflicts for me to fix today)

The actual changes from Sept 19 are not really relevant at this point - those interested can read the summary below or the actual merge log in the tree.

I have also applied the following patches for known problems:

sparc: qlogicpti fallout from sbus removal tip-core/powerpc: phys_addr_t has moved to linux/types.h
v9fs: don't export static functions
tpm: don't export static functions
mfd/wm8350: don't export static functions

----------------------------------------------------------------------------

I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/sfr/linux-next.git
(patches at
http://www.kernel.org/pub/linux/kernel/people/sfr/linux-next/). If you are tracking the linux-next tree using git, you should not use "git pull" to do so as that will try to merge the new linux-next release with the old one. You should use "git fetch" as mentioned in the FAQ on the wiki (see below).

You can see which trees have been included by looking in the Next/Trees file in the source. There are also quilt-import.log and merge.log files in the Next directory. Between each merge, the tree was built with a ppc64_defconfig for powerpc and an allmodconfig for x86_64. After the final fixups, it is also built with powerpc allnoconfig, 44x_defconfig and allyesconfig and i386, sparc and sparc64 defconfig.

Below is a summary of the state of the merge.

We are up to 120 trees (counting Linus' and 14 trees of patches pending for Linus' tree), more are welcome (even if they are currently empty). Thanks to those who have contributed, and to those who haven't, please do.

Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next . If maintainers want to give advice about cross compilers/configs that work, we are always open to add more builds.

Thanks to Jan Dittmer for adding the linux-next tree to his build tests at http://l4x.org/k/ , the guys at http://test.kernel.org/ and Randy Dunlap for doing many randconfig builds.

There is a wiki covering stuff to do with linux-next at
http://linux.f-seidel.de/linux-next/pmwiki/ . Thanks to Frank Seidel.

Huh, this makes very little sense to me... Can I talk you into trying the for-linus branch of the block tree?

Huh, this makes very little sense to me... Can I talk you into trying the for-linus branch of the block tree?

just to see if it reproduces with that. I'm assuming 2.6-git is fine?

I applied the for-linus branch on top of 2.6.27-git7 kernel and I was not able to reproduce with it.

OK, I'm guessing it's a merge mess in linux-next. I tried to look at the diff, but it was pretty much impossible to read and even included lots of things in -git already.

If you are looking at the linux-next patch on kernel.org, then it is relative to 2.6.27, so will contain a lot of stuff in Linus' tree. Its purpose is to allow people to recreate the linux-next tree from a kernel tarball.

In the linux-next git tree, the point in Linus' tree that it is based on the the "stable" branch. If necessary, people should be able to bisect between the "stabel" and "master" branches of a linux-next tree. Or, I am told, between one linux-next tree and another (but that sounds painful to me).

OK, I'll try the -git tree next time I have to lookup changes in -next. Thanks for the explanation!
