# commit 49ef015632ab3fcc19b2cb37b199d6d7ebcfa5f8
# Merge: 19caf581ba44 d8b5297f6d98
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sun Mar 24 11:16:27 2019 -0700
# 
#     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 ]
#     
#     * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (75 commits)
