Subject: [PATCH] mm: Remove useless vma parameter to offset_il_node
Date: Wed, 16 Aug 2017 18:09:15 +0200 [thread overview]
Message-ID: <1502899755-23146-1-git-send-email-ldufour@linux.vnet.ibm.com> (raw)
While reading the code I found that offset_il_node() has a vm_area_struct
pointer parameter which is unused.
