Subject[GIT pull] perf updates for 5.1
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

A larger set of perf updates:

Note, that not all of them are strictly fixes, but that's solely the tip
maintainers fault as they let the timely -rc1 pull request fall through
the cracks for various reasons including travel. 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

Thanks,

tglx

+AddressSanitizer (or ASan) is a GCC feature that detects memory corruption bugs
+such as buffer overflows and memory leaks.
+
+ $ cd tools/perf
+ $ make DEBUG=1 EXTRA_CFLAGS='-fno-omit-frame-pointer -fsanitize=address'

+ASan outputs all detected issues into a log file named 'asan.log.<pid>'.
+
+UndefinedBehaviorSanitizer (or UBSan) is a fast undefined behavior detector
+supported by GCC. UBSan detects undefined behaviors of programs at runtime.
+
+ $ cd tools/perf
