From 19ae89d32503493315dec77919815d3add851389 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 18 Dec 2017 12:25:19 +1100 Subject: [PATCH] staging: lustre: libcfs: remove wi_data from cfs_workitem In every case, the value passed via wi_data can be determined from the cfs_workitem pointer using container_of(). So use container_of(), and discard wi_data.
