From: Liang Jie <liangjie@lixiang.com> mainline inclusion from mainline-v6.14-rc1 commit e197f5ec3ad38ad0a014ed1ba672497bdf0550bb category: feature bugzilla: https://atomgit.com/openeuler/kernel/issues/8335 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commi... -------------------------------- Update the `dsq_hash_params` initialization to use `sizeof_field` for the `key_len` field instead of a hardcoded value. This improves code readability and ensures the key length dynamically matches the size of the `id` field in the `scx_dispatch_q` structure.
