Hi Linus,
A few fixes for the 6.6 kernel release:
- syzbot report on a crash on 32-bit arm with highmem, and went digging
to check for potentially similar issues and found one more (me)
- Fix a syzbot report with PROVE_LOCKING=y and setting up the ring in a
disabled state (me)
- Fix for race with CPU hotplut and io-wq init (Jeff)
Please pull!
