Subject: [PATCH v3 11/17] slab: Remove dead code from free_large_kmalloc()
Date: Fri, 24 Oct 2025 21:44:26 +0100	[thread overview]
Message-ID: <20251024204434.2461319-12-willy@infradead.org> (raw)
In-Reply-To: <20251024204434.2461319-1-willy@infradead.org>

All three callers of free_large_kmalloc() check PageLargeKmalloc
first so this warning is now unnecessary.
