The first is to remove a duplication of creating debugfs files that already exist and causes an error report to be printed due to the failure of the second creation. The second is a memory leak fix that was introduced in 3.14. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJTUGZwAAoJEKQekfcNnQGu7W8IAIAMBVfrWdP6cmGle4tGfhVE sHcwqTH+07oANQJ3eFwFs5wBMb08s3hXwUHUxXcpjyq2Bs+AHr0vSL/nqCG4k8Ap 2T4ntL7esC1BWKw2lVVVYD12FiL7grUXVlx/q0WE2NuhCzWzNRTyb8sKrPoCRUEB 3o5rAt9+45PKUb2k/eqGBGhK8b4XDz2Wtk5Gj6YB3xttse/yjjcuw0gWMHN1JWfm eRuQUUBDDGUGkfF98k1aLrjPZooT3LIAV8L8md5C3ebEcXSC/h86hTYCGXv3oBDO 8sxcT0zoQcLuFhjkYLL1J1lBW6gxaVh052jYmQwMppQMos+WID2un2E92Ccg49E= =BwLF -----END PGP SIGNATURE----- Merge tag 'trace-fixes-v3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "This contains two fixes.
