#     Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull perf updates from Thomas Gleixner:
#      "Perf updates and fixes:
#     
#       Kernel:
#        - Handle events which have the bpf_event attribute set as side band
#          events as they carry information about BPF programs.
#        - Add missing switch-case fall-through comments
#     
#       Libraries:
#        - Fix leaks and double frees in error code paths.
#        - Prevent buffer overflows in libtraceevent
#     
#       Tools:
#        - Improvements in handling Intel BT/PTS
#        - Add BTF ELF markers to perf trace BPF programs to improve output
#        - Support --time, --cpu, --pid and --tid filters for perf diff
#        - Calculate the column width in perf annotate as the hardcoded 6
#          characters for the instruction are not sufficient
#        - Small fixes all over the place"
#
