Subject: [PATCH] common/defrag: Skip defrag tests on DAX-enabled filesystems
Date: Tue, 2 Jun 2026 15:44:18 +0530 [thread overview]
Message-ID: <20260602101418.55131-1-disgoel@linux.ibm.com> (raw)
Online defragmentation is not supported on DAX-enabled filesystems
because DAX bypasses the page cache required for defrag operations.
Add check in _require_defrag() to skip tests when DAX is enabled,
avoiding false failures on ext4/301-304, ext4/308 and generic/018.
