Merge tag 'trace-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt: "Not much new with tracing for this release. Mostly just clean ups and minor fixes. Here's what else is new: - A new TRACE_EVENT_FN_COND macro, combining both _FN and _COND for those that want both. - New selftest to test the instance create and delete - Better debug output when ftrace fails" * tag 'trace-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (24 commits) ftrace: Fix the race between ftrace and insmod ftrace: Add infrastructure for delayed enabling of module functions x86: ftrace: Fix the comments for ftrace_modify_code_direct() tracing: Fix comment to use tracing_on over tracing_enable metag: ftrace: Fix the comments for ftrace_modify_code sh: ftrace: Fix the comments for ftrace_modify_code() ia64: ftrace: Fix the comments for ftrace_modify_code() ftrace: Clean up ftrace_module_init() code ftrace: Join functions ftrace_module_init() and ftrace_init_module() tracing: Introduce TRACE_EVENT_FN_COND macro tracing: Use seq_buf_used() in seq_buf_to_user() instead of len bpf: Constify bpf_verifier_ops structure ftrace: Have ftrace_ops_get_func() handle RCU and PER_CPU flags too ftrace: Remove use of control list and ops ftrace: Fix output of enabled_functions for showing tramp ftrace: Fix a typo in comment ftrace: Show all tramps registered to a record on ftrace_bug() ftrace: Add variable ftrace_expected for archs to show expected code ftrace: Add new type to distinguish what kind of ftrace_bug() tracing: Update cond flag when enabling or disabling a trigger ...
