Hi Linus,
The following changes since commit 99d26de2f6d79badc80f55b54bd90d4cb9d1ad90:
writeback: make the laptop_mode prototypes available unconditionally (2021-08-10 07:00:50 -0600)

dm crypt: use in_hardirq() instead of deprecated in_irq() (2021-08-20 16:25:07 -0400)
Please pull, thanks.
Mike
----------------------------------------------------------------
- Add DM infrastructure for IMA-based remote attestion. These changes
are the basis for deploying DM-based storage in a "cloud" that must
validate configurations end-users run to maintain trust. These DM
changes allow supported DM targets' configurations to be measured
via IMA. But the policy and enforcement (of which configurations are
valid) is managed by something outside the kernel (e.g. Keylime).
- Fix DM crypt scalability regression on systems with many cpus due to
percpu_counter spinlock contention in crypt_page_alloc().
- Use in_hardirq() instead of deprecated in_irq() in DM crypt.
- Add event counters to DM writecache to allow users to further assess
how the writecache is performing.
- Various code cleanup in DM writecache's main IO mapping function.
