Message-Id: <20250703073903.6952-1-libaokun@huaweicloud.com> Date: Thu, 3 Jul 2025 15:39:02 +0800 From: libaokun@...weicloud.com To: linux-ext4@...r.kernel.org Cc: tytso@....edu, adilger.kernel@...ger.ca, jack@...e.cz, linux-kernel@...r.kernel.org, yi.zhang@...wei.com, yangerkun@...wei.com, libaokun1@...wei.com, libaokun@...weicloud.com Subject: [PATCH 1/2] ext4: show the default enabled i_version option From: Baokun Li <libaokun1@...wei.com> Display `i_version` in `/proc/fs/ext4/sdx/options`, even though it's default enabled. This aids users managing multi-version scenarios and simplifies debugging.
