So I'm # sending this nevertheless because rebasing and distangling fixes and # updates would be a mess and risky as well. As of tomorrow, a strict # fixes separation is happening again. Sorry for the slip-up. # # Kernel: # # - Handle RECORD_MMAP vs. RECORD_MMAP2 correctly so different # consumers of the mmap event get what they requested. # # Tools: # # - A larger set of updates to perf record/report/scripts vs. time # stamp handling # # - More Python3 fixups # # - A pile of memory leak plumbing # # - perf BPF improvements and fixes # # - Finalize the perf.data directory storage" # # [ Note: the kernel part is strictly a fix, the updates are purely to # tooling - Linus ] # # * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (75 commits) # perf bpf: Show more BPF program info in print_bpf_prog_info() # perf bpf: Extract logic to create program names from perf_event__synthesize_one_bpf_prog() # perf tools: Save bpf_prog_info and BTF of new BPF programs # perf evlist: Introduce side band thread # perf annotate: Enable annotation of BPF programs # perf build: Check what binutils's 'disassembler()' signature to use # perf bpf: Process PERF_BPF_EVENT_PROG_LOAD for annotation # perf symbols: Introduce DSO_BINARY_TYPE__BPF_PROG_INFO # perf feature detection: Add -lopcodes to feature-libbfd # perf top: Add option
