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. 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" * tag 'trace-v5.19-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: samples: Use KSYM_NAME_LEN for kprobes fprobe/samples: Make sample_probe static blk-iocost: tracing: atomic64_read(&ioc->vtime_rate) is assigned an extra semicolon ftrace: Be more specific about arch impact when function tracer is enabled tracing: Fix sleeping while atomic in kdb ftdump tracing/histograms: Fix memory leak problem
