Linus Torvalds b047602d57 Fixes and minor clean ups for tracing: ... - Fix memory leak by reverting what was thought to be a double free. A static tool had gave a false positive that a double free was possible in the error path, but it was actually a different location that confused the static analyzer (and those of us that reviewed it). - Move use of static buffers by ftrace_dump() to a location that can be used by kgdb's ftdump(), as it needs it for the same reasons. - Clarify in the Kconfig description that function tracing has negligible impact on x86, but may have a bit bigger impact on other architectures. - Remove unnecessary extra semicolon in trace event. - Make a local variable static that is used in the fprobes sample - Use KSYM_NAME_LEN for length of function in kprobe sample and get rid of unneeded macro for the same purpose. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYs3fgBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qlIKAQC9uvEb7fVduv834yU/HiPBbjYjZ7x5 q+G/6EbNVE5htwEA91IU90YdmCPDOkXovuUlTNB/1igvugFPQgR2BwIqgAQ= =+4E5 -----END PGP SIGNATURE----- Merge tag 'trace-v5.19-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "Fixes and minor clean ups for tracing: - Fix memory leak by reverting what was thought to be a double free.
