When doing my namespace checks, I find lots of local functions declared global (and dead code) in ALSA. Which tree is used for submitting patches for -next?

For sound/* in general, use my sound.git tree for-next branch. git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git

For sound/soc/*, maybe better to use Mark's sound git tree. git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

Mark is managing many small topic branches, but for-next branch should be available to make patches, at least.

Some examples from 'make namespacecheck'

There are quite lots of hits indeed. But I see a few of them are false-positive (depending on kconfig) and a few would be still better to keep for API consistency. If you can give a complete list beforehand, we can sort out such.

Ideally, it'd be best if we have a on-demand loading of library code in the kernel, instead of loading a whole "library module"...

thanks,

Takashi
