Message-ID: <20100212000016.GA25781@linux.vnet.ibm.com> Date: Thu, 11 Feb 2010 16:00:16 -0800 From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com> To: linux-kernel@...r.kernel.org Cc: mingo@...e.hu, laijs@...fujitsu.com, dipankar@...ibm.com, akpm@...ux-foundation.org, mathieu.desnoyers@...ymtl.ca, josh@...htriplett.org, dvhltc@...ibm.com, niv@...ibm.com, tglx@...utronix.de, peterz@...radead.org, rostedt@...dmis.org, Valdis.Kletnieks@...edu, dhowells@...hat.com Subject: [PATCH tip/core/rcu 0/13] rcu: add lockdep checking, doc update, dyntick GP acceleration Hello! The first 11 patches extend lockdep to check for proper protection of rcu_dereference(), described in http://lwn.net/Articles/371986/, and apply these lockdep extensions in a number of areas in the kernel. There are likely more such changes required, as I am limited to those located by the systems I have access to. The twelfth patch is a documentation update, and the last patch accelerates grace periods when the current CPU is the last non-dyntick-idle CPU in the system, which is important for some multi-core battery-powered devices. b/Documentation/RCU/00-INDEX | 2 b/Documentation/RCU/RTFP.txt | 6 + b/Documentation/RCU/checklist.txt | 34 ++++++---- b/Documentation/RCU/lockdep.txt | 67 ++++++++++++++++++++ b/Documentation/RCU/whatisRCU.txt | 14 ++-- b/fs/file.c | 2 b/fs/proc/array.c | 2 b/fs/proc/base.c | 6 + b/include/linux/cgroup.h | 5 + b/include/linux/cpumask.h | 14 ++++ b/include/linux/cred.h | 2 b/include/linux/fdtable.h | 9 +- b/include/linux/lockdep.h | 4 + b/include/linux/rculist.h | 14 ++-- b/include/linux/rculist_nulls.h | 5 - b/include/linux/rcupdate.h | 126 ++++++++++++++++++++++++++++++++++---- b/include/linux/rtnetlink.h | 3 b/include/linux/srcu.h | 87 +++++++++++++++++++++++++- b/include/net/addrconf.h | 4 - b/init/Kconfig | 16 ++++ b/init/main.c | 2 b/kernel/cgroup.c | 12 +++ b/kernel/exit.c | 14 +++- b/kernel/fork.c | 1 b/kernel/lockdep.c | 19 +++++ b/kernel/notifier.c | 6 - b/kernel/pid.c | 2 b/kernel/rcupdate.c | 10 +++ b/kernel/rcutorture.c | 12 +++ b/kernel/rcutree.c | 5 - b/kernel/rcutree_plugin.h | 70 ++++++++++++++++++++- b/kernel/sched.c | 12 ++- b/kernel/srcu.c | 50 +++++++++------ b/lib/Kconfig.debug | 12 +++ b/lib/debug_locks.c | 2 b/lib/idr.c | 9 +- b/lib/radix-tree.c | 25 +++---- b/net/core/dev.c | 2 b/net/core/filter.c | 6 - b/net/core/rtnetlink.c | 8 ++ b/net/core/sock.c | 3 b/net/decnet/dn_route.c | 14 ++-- b/net/ipv4/route.c | 14 ++-- b/net/packet/af_packet.c | 3 b/security/keys/gc.c | 3 b/security/keys/keyring.c | 5 - include/linux/rcupdate.h | 45 ++++++++++--- include/linux/srcu.h | 9 ++ 48 files changed, 657 insertions(+), 140 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
