Subject: [PATCH] mm: memory-failure: remove unneeded page state check in shake_page()
Date:   Sun, 25 Jun 2023 19:34:30 +0800

Remove unneeded PageLRU(p) and is_free_buddy_page(p) check as slab caches
are not shrunk now. This check can be added back when a lightweight range
based shrinker is available.
