Subject: [PATCH] dma/pool: eliminate alloc_pages warning in atomic_pool_expand
Date: Tue, 2 Dec 2025 09:28:10 -0600 [thread overview]
Message-ID: <20251202152810.142370-1-dave.kleikamp@oracle.com> (raw)
atomic_pool_expand iterately tries the allocation while decrementing the
page order. There is no need to issue a warning if an attempted
allocation fails.
