Subject: [GIT PULL] Multi-gen LRU for 5.18-rc1
Hi Linus,
This is more of an option than a request for 5.18. I'm sending it to
you directly because, in my judgement, it's now as ready as it'll ever
be.
Thanks!
The following changes since commit 46f538bf2404ee9c32648deafb886f49144bfd5e:
Merge tag 'backlight-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/backlight (2022-03-25 14:01:23 -0700)
are available in the Git repository at:

----------------------------------------------------------------
Multi-gen LRU for 5.18-rc1
This series was retested on top of 5.18-ed4643521e6a. All previous
comments have been addressed.
Changes since v8 [1]
* Removed two user-hostile config options (suggested by Linus
Torvalds).
Changes since v9 [2]
* Resolved the conflicts with the latest folio changes.
* Switched to spin_trylock() to move onto the next page table rather
than spin on the current one when trying to clear the accessed
bit on many page tables.
* Added introductory paragraphs to the admin guide and the design
doc (suggested by Mike Rapoport).
* Expanded comments in get_nr_evictable() (suggested by Barry Song
and Aneesh Kumar).
* Expanded comments in inc_max_seq() (suggested by Barry Song).
