There's been pressure to allow non root to tracefs # in a controlled fashion, and using groups is probably the safest. # # - Bootconfig memory managament updates. # # - Bootconfig clean up to have the tools directory be less dependent on # changes in the kernel tree. # # - Allow perf to be traced by function tracer. # # - Rewrite of function graph tracer to be a callback from the function # tracer instead of having its own trampoline (this change will happen # on an arch by arch basis, and currently only x86_64 implements it). # # - Allow multiple direct trampolines (bpf hooks to functions) be batched # together in one synchronization. # # - Allow histogram triggers to add variables that can perform # calculations against the event's fields. # # - Use the linker to determine architecture callbacks from the ftrace # trampoline to allow for proper parameter prototypes and prevent # warnings from the compiler. # # - Extend histogram triggers to key off of variables. # # - Have trace recursion use bit magic to determine preempt context over # if branches. # # - Have trace recursion disable preemption as all use cases do anyway. # # - Added testing for verification of tracing utilities. # # - Various small clean ups and fixes. # # * tag 'trace-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (101 commits) #
