If anyone has any objections, please let me know. ------------------ From: Christoph Hellwig [ Upstream commit 2430e3380936df0b648af720cae624eef035a2d1 ] bfs uses buffer_heads, which don't handle block size > PAGE_SIZE well. Without this, mounting will hit the BUG_ON(offset >= folio_size(folio)); in folio_set_bh on the first __bread_gfp call.
