From b972d0797180d8414351d9dc8ff65071c692d058 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 29 Sep 2014 10:46:22 +1000 Subject: [PATCH] xfs: annotate user variables passed as void Some argument callbacks can contain user buffers, and sparse warns about passing them as void pointers. Cast appropriately to remove the sparse warnings.
