The array is intended\nto be a flexible length array, so the WARN is a false positive.\n\nTo suppress the WARN, remove the constant number '1' from the array\ndeclaration and clarify that it has flexible length. Also, adjust the\nmemory allocation size to match the change.\n\ud83d\udccf Published: 2024-05-30T15:29:15.121Z\n\ud83d\udccf Modified: 2025-01-15T12:49:28.540Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/5f0266044dc611563539705bff0b3e1545fbb6aa\n2. https://git.kernel.org/stable/c/f09318244c6cafd10aca741b9c01e0a2c362d43a\n3. https://git.kernel.org/stable/c/4d2772324f43cf5674ac3dbe3f74a7e656396716\n4. https://git.kernel.org/stable/c/429846b4b6ce9853e0d803a2357bb2e55083adf0", "creation_timestamp": "2025-01-15T13:11:52.000000Z"}
