From: Yi Liu Date: Thu, 29 Jan 2026 09:49:00 +0000 (+0800) Subject: RDMA/uverbs: Add __GFP_NOWARN to ib_uverbs_unmarshall_recv() kmalloc X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=58b604dfc7bb753f91bc0ccd3fa705e14e6edfb4;p=thirdparty%2Fkernel%2Flinux.git RDMA/uverbs: Add __GFP_NOWARN to ib_uverbs_unmarshall_recv() kmalloc Since wqe_size in ib_uverbs_unmarshall_recv() is user-provided and already validated, but can still be large, add __GFP_NOWARN to suppress memory allocation warnings for large sizes, consistent with the similar fix in ib_uverbs_post_send().
