Some of the fixes need to go back to 3.10. They are minor, and deal mostly with incorrect ref counting in accessing event files. There was a couple of optimizations that should have perf perform a bit better when accessing trace events. And some various clean ups. Some of the clean ups are necessary to help in a fix to a theoretical race between opening a event file and deleting that event. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQEcBAABAgAGBQJR7TuSAAoJEOdOSU1xswtMFsEIALOQWth+jUEmd+TJNMgW7vHd aJ4pjc0Br2ur0XOm4xsOOsuexQ/sKG4J0qJT4z01Ny4ZJ6UcL6CvLKlQXlySrUw5 POH6+7B7os3ikav+4KGDYJpeyR7l+uveA7IcqZz5OWAbz2yi3HbluPUUyFn+62ic Q0IOi4KkCly4buHNqJqfQRUo+0eBb8sZUfaklIQE07Dd66YVyq4w2WogI2PxBanP b6p4sE9n7wf7GxXXur5jPBz8PheAFu6a6dM9d9BX28ia79OGSGN4mYWbSNOn8wzl gJr1ZqxKJBq73IHpNV7QBOCCgDJ9vtuqxKKm4kuLCMfjCTPBsQ3Bmo/qJulnnGI= =AlmI -----END PGP SIGNATURE----- Merge tag 'trace-3.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes and cleanups from Steven Rostedt: "This contains fixes, optimizations and some clean ups Some of the fixes need to go back to 3.10.
