From 7d26842fd43cb0f7e29c9f8e98af9091ccb0aef5 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Thu, 13 Nov 2025 00:09:25 +0000 Subject: [PATCH] slab: Remove folio references from kfree_rcu_sheaf() In preparation for splitting struct slab from struct page and struct folio, remove mentions of struct folio from this function. Since we don't need to handle large kmalloc objects specially here, we can just use virt_to_slab().
