Linus Torvalds b72b5fecc1 tracing updates for 6.3: ... - Add function names as a way to filter function addresses - Add sample module to test ftrace ops and dynamic trampolines - Allow stack traces to be passed from beginning event to end event for synthetic events. This will allow seeing the stack trace of when a task is scheduled out and recorded when it gets scheduled back in. - Add trace event helper __get_buf() to use as a temporary buffer when printing out trace event output. - Add kernel command line to create trace instances on boot up. - Add enabling of events to instances created at boot up. - Add trace_array_puts() to write into instances. - Allow boot instances to take a snapshot at the end of boot up. - Allow live patch modules to include trace events - Minor fixes and clean ups -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCY/PaaBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qh5iAPoD0LKZzD33rhO5Ec4hoexE0DkqycP3 dvmOMbCBL8GkxwEA+d2gLz/EquSFm166hc4D79Sn3geCqvkwmy8vQWVjIQc= =M82D -----END PGP SIGNATURE----- Merge tag 'trace-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Add function names as a way to filter function addresses - Add sample module to test ftrace ops and dynamic trampolines - Allow stack traces to be passed from beginning event to end event for synthetic events.
