| |
Hello!
This patchset shows the patches queued for 2.6.36/7. These are not yet ready to move upstream due to dependencies on commits moving up other trees. The patches are as follows:
1-19. These are the remaining patches implementing Arnd's sparse-checking work. #1 needs to go up the networking tree, but will cause regressions until f5155b33277 ("rcu: add an rcu_dereference_index_check()") reaches mainline. #2 depends on #1, and many of the later patches (#3-#30) depend on #2. Many of #3-#19 will go up non-tip trees. 20. Update Documentation/RCU to remove the now-deprecated rcu_head initialization macros. 21. Fix long-standing DocBook example showing long-dead three-argument variant of call_rcu(). 22. Make the CPU stall warning timeout configurable at build time with new RCU_CPU_STALL_TIMEOUT config parameter. 23. Remove the now-deprecated rcu_head initialization macros. This depends on a couple of patches removing their use that are making their way up other maintainer trees. 24. Document the new debug assists from Arnd, Mathieu, and myself. 25. Add random preemption to rcutorture testing of preemptible RCU, courtesy of Lai Jiangshan. 26. Remove TREE_RCU's ->rda[] array in favor of the new __percpu facility, also courtesy of Lai Jiangshan. 27. Fixlet to #26 for RCU tracing. 28. Rename __do_rcu_dereference_check() to rcu_lockdep_assert(), given that Tetsuo Handa has found outside-of-RCU use for this function. 29. Add a boot parameter to suppress RCU CPU stall warnings. 30. Update kerneldoc or rcu_read_lock(), call_rcu(), and synchronize_rcu().
For a testing-only git-tree version of this patchset, see:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/testing
By "testing-only" I mean that any of the commits in the rcu/testing branch might be folded, spindled, or otherwise mutilated at any time. ;-)
Thanx, Paul
