From acb6d4cb84205a8e3f19ca470cfcf7bf6d93a509 Mon Sep 17 00:00:00 2001 From: Disha Goel Date: Mon, 8 Jun 2026 15:53:28 +0530 Subject: [PATCH] common/defrag: skip defrag tests on DAX-enabled filesystems Online defragmentation is not supported on ext4 DAX-enabled filesystems. The ext4 defrag ioctl (EXT4_IOC_MOVE_EXT) returns EOPNOTSUPP when used on DAX files. Add an ext4-specific check in _require_defrag() to skip tests when DAX is enabled, avoiding false failures on ext4/301-304, ext4/308, and generic/018. XFS defrag works with DAX, so this check is ext4-specific. Suggested-by: Darrick J.
