Some of the bpf maps are created with __GFP_NOWARN, i.e. arraymap, bloom_filter, bpf_local_storage, bpf_struct_ops, lpm_trie, queue_stack_maps, reuseport_array, stackmap and xskmap, while others are created without __GFP_NOWARN, i.e. cpumap, devmap, hashtab, local_storage, offload, ringbuf and sock_map. But there are not key differences between the creation of these maps. So let make this allocation flag consistent in all bpf maps creation. Then we can use a generic helper to alloc all bpf maps.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
