Subject[GIT pull] perf updates for 5.1
From
Date
Linus,

please pull the latest perf-urgent-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-for-linus

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

Thanks,

tglx

+--time::
+ Analyze samples within given time window. It supports time
