| |
Hello, Ingo,
Here are the final commits from Mathieu's debugobjects series and the first few from Arnd's RCU-pointer sparse series. The first three remove RCU's (useless) initializations from mm, fs, and powerpc:
mm: http://lkml.org/lkml/2010/5/18/562 fs: http://lkml.org/lkml/2010/5/18/500 powerpc:http://www.mail-archive.com/linuxppc-dev@lists.ozlabs.org/msg43510.html
Kosaki Motohiro agreed that the mm patch should go up -tip, and none of the other maintainers objected to the prospect of their patches going up -tip.
The fourth patch removes RCU's initialization definitions, and the final four patches provide the beginnings of Arnd's RCU-pointer sparse checks.
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/next
Or, if you prefer this against 2.6.34-rc7 without a merge record:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/next-rc7
If you would rather me rebase this stack against 2.6.35-rc1, let me know!
Either way, once these commits reach mainline, I will submit the next 21 commits to their respective trees. The maintainers have been CCed on the earlier LKML patchsets (http://lkml.org/lkml/2010/5/12/372). Once these 21 commits hit mainline, I will send you a pull request for the remaining two commits.
Then on to CONFIG_TINY_PREEMPT_RCU.
Thanx, Paul
