From 044472d5ee7d71f918fa3f61bd65e4933a0c006e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 29 Jun 2026 14:17:38 +0200 Subject: iomap: consolidate bio submission Add a iomap_bio_submit_read_endio helper factored out of iomap_bio_submit_read to that all ->submit_read implementations for iomap_read_ops that use iomap_bio_read_folio_range can shared the logic. Right now that logic is mostly trivial, but already has a bug for XFS because the XFS version is too trivial: file system integrity validation needs a workqueue context and thus can't happen from the default iomap bi_end_io I/O handler. Unfortunately the iomap refactoring just before fs integrity landed moved code around here and the call go misplaced, meaning it never got called. The PI information still is verified by the block layer, but the offloading is less efficient (and the future userspace interface can't get at it).
