From e197f5ec3ad38ad0a014ed1ba672497bdf0550bb Mon Sep 17 00:00:00 2001 From: Liang Jie Date: Fri, 13 Dec 2024 17:52:54 +0800 Subject: [PATCH] sched_ext: Use sizeof_field for key_len in dsq_hash_params 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.
