From f02c75e630f09ff4906b0839ed0eaa37c2316132 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 8 Jun 2023 11:11:33 +0200 Subject: [PATCH] btrfs: set FMODE_CAN_ODIRECT instead of a dummy direct_IO method Since commit a2ad63daa88b ("VFS: add FMODE_CAN_ODIRECT file flag") file systems can just set the FMODE_CAN_ODIRECT flag at open time instead of wiring up a dummy direct_IO method to indicate support for direct I/O. Do that for btrfs so that noop_direct_IO can eventually be removed.
