o Pretty much a full rewrite of the processing of function plugins. i.e. echo do_IRQ:stacktrace > set_ftrace_filter o The rewrite was needed to add plugins to be unique to tracing instances. i.e. mkdir instance/foo; cd instances/foo; echo do_IRQ:stacktrace > set_ftrace_filter The old way was written very hacky. This removes a lot of those hacks. o New "function-fork" tracing option. When set, pids in the set_ftrace_pid will have their children added when the processes with their pids listed in the set_ftrace_pid file forks. o Exposure of "maxactive" for kretprobe in kprobe_events o Allow for builtin init functions to be traced by the function tracer (via the kernel command line). Module init function tracing will come in the next release. o Added more selftests, and have selftests also test in an instance. -----BEGIN PGP SIGNATURE----- iQExBAABCAAbBQJZCRchFBxyb3N0ZWR0QGdvb2RtaXMub3JnAAoJEMm5BfJq2Y3L zuIH/RsLUb8Hj6GmhAvn/tblUDzWyqlXX2h79VVlo/XrWayHYNHnKOmua1WwMZC6 xESXb/AffAc89VWTkKsrwaK7yfRPG6+w8zTZOcFuXSBpqSGG/oey9Fxj5Wqqpche oJ2UY7ngxANAipkP5GxdYTafFSoWhGZGfUUtW+5tAHoFHzqO2lOjO8olbXP69sON kVX/b461S20cVvRe5H/F0klXLSc37Tlp5YznXy4H4V4HcJSN1Fb6/uozOXALZ4se SBpVMWmVVoGJorzj+ic7gVOeohvC8RnR400HbeMVwaI0Lj50noidDj/5Hv8F7T+D h1B8vATNZLFAFUOSHINCBIu6Vj0= =t8mg -----END PGP SIGNATURE----- Merge tag 'trace-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "New features for this release: - Pretty much a full rewrite of the processing of function plugins. i.e. echo do_IRQ:stacktrace > set_ftrace_filter - The rewrite was needed to add plugins to be unique to tracing instances. i.e. mkdir instance/foo; cd instances/foo; echo do_IRQ:stacktrace > set_ftrace_filter The old way was written very hacky.
