From 9636e650e16f6b01f0044f7662074958c23e4707 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 25 Jan 2023 07:58:39 +0100 Subject: fs: build the legacy direct I/O code conditionally Add a new LEGACY_DIRECT_IO config symbol that is only selected by the file systems that still use the legacy blockdev_direct_IO code, so that kernels without support for those file systems don't need to build the code.
