linux-next: Tree for July 12

linux-next: Tree for July 12

Hi all,

Changes since 20100709:

The vfs tree gained a build failure for which I applied a merge fix patch.

The v4l-dvb tree lost its conflict.

The infiniband tree lost its build failure.

The block tree lost its build failure and all but one conflict.

The trivial tree lost its conflict.

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

I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/v2.6/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 (if any), it is also built with powerpc allnoconfig (32 and
64 bit), ppc44x_defconfig and allyesconfig (minus
CONFIG_PROFILE_ALL_BRANCHES - this fails its final link) and i386, sparc
and sparc64 defconfig. These builds also have
CONFIG_ENABLE_WARN_DEPRECATED, CONFIG_ENABLE_MUST_CHECK and
CONFIG_DEBUG_INFO disabled when necessary.

Below is a summary of the state of the merge.

We are up to 164 trees (counting Linus' and 22 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.

Greg,
What is there about debugfs that requires sysfs?

(lib/Kconfig.debug:)

config DEBUG_FS
	bool "Debug Filesystem"
	depends on SYSFS

I ask because kconfig now (in linux-next) warns about kconfig dependency
problems, like this one:

warning: (TREE_RCU_TRACE || AMD_IOMMU_STATS && AMD_IOMMU || MTD_UBI_DEBUG && MTD && SYSFS && MTD_UBI || UBIFS_FS_DEBUG && MISC_FILESYSTEMS && UBIFS_FS || DEBUG_KMEMLEAK && DEBUG_KERNEL && EXPERIMENTAL && !MEMORY_HOTPLUG && (X86 || ARM || PPC || S390 || SPARC64 || SUPERH || MICROBLAZE) && SYSFS || TRACING || X86_PTDUMP && DEBUG_KERNEL || BLK_DEV_IO_TRACE && TRACING_SUPPORT && FTRACE && SYSFS && BLOCK) selects DEBUG_FS which has unmet direct dependencies (SYSFS)

because TREE_RCU_TRACE selects DEBUG_FS, even when SYSFS is not enabled.
I first made a patch to have TREE_RCU_TRACE depend on SYSFS, but then I just
removed the DEBUG_FS "depends on SYSFS" and the kernel builds fine,
hence the first question.

thanks,

Look at commit 3348e05a4f25489908d9f7ed4e80ac291ead18f4 almost 5 years
ago:
    [PATCH] DEBUG_FS must depend on SYSFS
    
    CONFIG_DEBUG_FS=y and CONFIG_SYSFS=n results in the following compile
    error:
    
    <--  snip  -->
    
    ...
      LD      vmlinux
    fs/built-in.o: In function `debugfs_init':
    inode.c:(.init.text+0x31be): undefined reference to `kernel_subsys'
    make: *** [vmlinux] Error 1
    
    <--  snip  -->

But, there is no "kernel_subsys" anymore, it is called kernel_kobj, and
is in kernel/ksysfs.c and always is built now, even if CONFIG_SYSFS is
disabled.

So it should be safe to remove that dependancy if you want to.

[PATCH -next] debugfs: no longer needs to depend on SYSFS

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@oracle.com>

debugfs no longer uses 'kernel_subsys' (which is gone), and other
kernel/ksysfs.c code is always built, so DEBUG_FS does not need
to depend on SYSFS.

Fixes this kconfig warning:

warning: (TREE_RCU_TRACE || AMD_IOMMU_STATS && AMD_IOMMU || MTD_UBI_DEBUG && MTD && SYSFS && MTD_UBI || UBIFS_FS_DEBUG && MISC_FILESYSTEMS && UBIFS_FS || DEBUG_KMEMLEAK && DEBUG_KERNEL && EXPERIMENTAL && !MEMORY_HOTPLUG && (X86 || ARM || PPC || S390 || SPARC64 || SUPERH || MICROBLAZE) && SYSFS || TRACING || X86_PTDUMP && DEBUG_KERNEL || BLK_DEV_IO_TRACE && TRACING_SUPPORT && FTRACE && SYSFS && BLOCK) selects DEBUG_FS which has unmet direct dependencies (SYSFS)
