Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Thomas Gleixner:
"A larger set of perf updates.
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"
[ Note: the kernel part is strictly a fix, the updates are purely to
tooling - Linus ]
