From f9f7500521b25dbf1aba476b81230489ad8e2c4b Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Sun, 8 Jan 2006 01:00:33 -0800 Subject: [PATCH] [PATCH] slab: remove unused align parameter from alloc_percpu __alloc_percpu and alloc_percpu both take an 'align' argument which is completely ignored. snmp6_mib_init() in net/ipv6/af_inet6.c attempts to use it, but it will be ignored. Therefore, remove the 'align' argument and fixup the lone caller.
