Subject: [PATCH] drm/ttm: Fix hardcoded LRU index in ttm_device_fini()
Date: Wed, 15 Jul 2026 16:58:23 +0800 [thread overview]
Message-ID: <20260715085823.25671-1-hongfu.li@linux.dev> (raw)
From: Hongfu Li <lihongfu@kylinos.cn>
ttm_device_fini() iterates over all TTM_MAX_BO_PRIORITY LRU lists
using loop variable i, but list_empty() always checks man->lru[0]
instead of man->lru[i]. This means the debug message only checks
priority 0 and prints the same result four times.
Fixes: 8af8a109b34f ("drm/ttm: device naming cleanup")
