Its filename was mm-mmu_gather-clean-up-the-stale-code-comment.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Baoquan He Subject: mm/mmu_gather: clean up the stale code comment Date: Tue, 11 Feb 2025 11:43:48 +0800 In commit d7f861b9c43a ("mm/mmu_gather: add __tlb_remove_folio_pages()"), helper function __tlb_remove_folio_pages_size() was added. And based on the helper, wrapper functions __tlb_remove_folio_pages() and __tlb_remove_page_size() are created and used by upper level functions. So let's update the code comment to reflect the current code about tlb_remove_page()/tlb_remove_page_size(), etc. Link: https://lkml.kernel.org/r/20250211034348.39531-2-bhe@redhat.com Signed-off-by: Baoquan He Cc: "Aneesh Kumar K.V" Cc: Nicholas Piggin Cc: Peter Zijlstra (Intel) Cc: Qi Zheng Cc: Will Deacon Signed-off-by: Andrew Morton --- include/asm-generic/tlb.h | 23 +++++++++++------------ 1 file changed, 11 insertions(+), 12 deletions(-) --- a/include/asm-generic/tlb.h~mm-mmu_gather-clean-up-the-stale-code-comment +++ a/include/asm-generic/tlb.h @@ -67,22 +67,21 @@ * * See also MMU_GATHER_TABLE_FREE and MMU_GATHER_RCU_TABLE_FREE. * - * - tlb_remove_page() / __tlb_remove_page() - * - tlb_remove_page_size() / __tlb_remove_page_size() - * - __tlb_remove_folio_pages() - * - * __tlb_remove_page_size() is the basic primitive that queues a page for - * freeing. __tlb_remove_page() assumes PAGE_SIZE.
