Its filename was rdma-cxgb4-remove-dead-null-checks-after-gfp_nofail-allocations.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Gou Hao Subject: RDMA/cxgb4: remove dead NULL checks after GFP_NOFAIL allocations Date: Fri, 24 Jul 2026 10:28:51 +0800 alloc_skb() with the __GFP_NOFAIL flag will never return NULL, so the subsequent NULL checks and error handling are unreachable dead code. Remove them.
