Subject: [PATCH] ext4: EXT4_I(sbi->s_buddy_cache)->i_state_flags is not initialized
Date: Tue, 27 Jan 2026 17:34:10 +0800 [thread overview]
Message-ID: <20260127-origin-dev-v1-1-cafda25e307f@amlogic.com> (raw)
From: Jiucheng Xu <jiucheng.xu@amlogic.com>
The i_state_flags originates from an inode that was previously
destroyed and then allocated to s_buddy_cache; it requires
reinitialization.
The relevant log during umount is shown below:
EXT4-fs (mmcblk0p28): unmounting filesystem xxx-xxx
EXT4-fs (mmcblk0p28): Inode 1 (39878178): inode tracked as orphan!
