Date: Wed, 12 May 2010 14:33:17 -0700 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, eric.dumazet@...il.com Subject: [PATCH tip/core/rcu 0/23] infrastructure for sparse checks for RCU usage Hello! This patchset pulls Arnd's sparse-checking commits out of the earlier patchbomb (http://lkml.org/lkml/2010/5/4/298): 1. Add an rcu_dereference_check() API in order to continue supporting the array-index use cases that would otherwise be invalidated by this change. 2. Add an empty __rcu annotation API to reduce inter-commit dependency. 3-5. Updates to vfs, net, and mce to avoid breakage by later commits. 6. Introduce sparse __rcu functionality. 7. Update rculist primitives to avoid false positives. 8-22. Introduce __rcu annotations to cgroups, credentials, keys, nfs, net, perf_event, notifiers, radix-tree, idr, input, net-netfilter, kvm, and kernel. 23. Introduce __rcu annotations and checks to vhost. These have been reordered and consolidated to reduce inter-commit dependencies.
