From 259e19145e1fa9bb9e502f625f7bce1a0c078fa0 Mon Sep 17 00:00:00 2001 From: Jan Dakinevich Date: Mon, 9 Jul 2018 16:51:03 +0300 Subject: [PATCH] IPoIB: use kvzalloc to allocate an array of bucket pointers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This table by default takes 32KiB which is 3rd memory order. Meanwhile, this memory is not aimed for DMA operation and could be safely allocated by vmalloc.
