From 5b31ca56f0af4d67d659de62bd13f77cae9b6aba Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Sun, 20 Sep 2026 22:28:09 -0400 Subject: md: use folio_alloc_buffers() Remove the last user of alloc_page_buffers(). Use folio_alloc_buffers() instead, since alloc_page_buffers() is a wrap over it. Although the pages used in md-bitmap are not folios, as they are not mapped into userspace nor enter the page cache, but they still have buffer heads attached. Cleaning up the code to not use buffer heads is future work.
