Merge branch 'core/rcu' into perf/core
Steve Rostedt asked for the merge of a single commit, into both the RCU and the perf/tracing tree: | Josh made a change to the tracing code that affects both the | work Paul McKenney and I are currently doing. At the last | Kernel Summit back in August, Linus said when such a case | exists, it is best to make a separate branch based off of his | tree and place the change there. This way, the repositories | that need to share the change can both pull them in and the | SHA1 will match for both. Whichever branch is pulled in first | by Linus will also pull in the necessary change for the other | branch as well. Signed-off-by: Ingo Molnar <[email protected]>
