Long Li 05aba2d316 sunrpc: fix race in cache cleanup causing stale nextcheck time ... [ Upstream commit 2298abcbe1 ] When cache cleanup runs concurrently with cache entry removal, a race condition can occur that leads to incorrect nextcheck times. This can delay cache cleanup for the cache_detail by up to 1800 seconds: 1. cache_clean() sets nextcheck to current time plus 1800 seconds 2. While scanning a non-empty bucket, concurrent cache entry removal can empty that bucket 3. cache_clean() finds no cache entries in the now-empty bucket to update the nextcheck time 4. This maybe delays the next scan of the cache_detail by up to 1800 seconds even when it should be scanned earlier based on remaining entries Fix this by moving the hash_lock acquisition earlier in cache_clean(). This ensures bucket emptiness checks and nextcheck updates happen atomically, preventing the race between cleanup and entry removal.
