This problem can be\nfixed the same way, however, the code will be complex.\n\nHence switch to use list_for_each_entry, in this case mddev_put() can free\nthe mddev1 and it's not safe as well. Refer to md_seq_show(), also factor\nout a helper mddev_put_locked() to fix this problem.\n\ud83d\udccf Published: 2025-04-16T14:13:09.399Z\n\ud83d\udccf Modified: 2025-04-25T10:06:48.152Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/ca9f84de76723b358dfc0606668efdca54afc2e5\n2. https://git.kernel.org/stable/c/d69a23d8e925f8052d657652a6875ec2712c7e33\n3. https://git.kernel.org/stable/c/e2a9f73ee408a460f4c9dfe03b4741d6b11652b8\n4. https://git.kernel.org/stable/c/5462544ccbad3fc938a71b01fa5bd3a0dc2b750a\n5. https://git.kernel.org/stable/c/8542870237c3a48ff049b6c5df5f50c8728284fa", "creation_timestamp": "2025-04-25T11:07:40.000000Z"} 2025-04-25T11:07:40+00:00
