Subject: [PATCH 1/4] lib/rhashtable: simplify bucket_table_alloc()
Date:   Thu, 21 Jun 2018 14:28:22 -0700
Message-Id: <20180621212825.3059-2-dave@stgolabs.net>
In-Reply-To: <20180621212825.3059-1-dave@stgolabs.net>
References: <20180621212825.3059-1-dave@stgolabs.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

As of ce91f6ee5 (mm: kvmalloc does not fallback to vmalloc for incompatible gfp flag),
we can simplify the caller and trust kvzalloc() to just do the right thing.
