Description

While building with the latest recipe for sles11sp2 server from LU-1812, I discovered a new build failure. Errors look like:

  CC [M]  /home/bogl/lustre-release/lustre/mdt/mdt_handler.o
cc1: warnings being treated as errors
/home/bogl/lustre-release/lustre/mdt/mdt_handler.c: In function ‘mdt_path_current’:

I believe this failure came from code added in recent commit a19f706ebef23a5778572553256df78abb81e1a4, LU-2801 mdt: checking remote object in mdt_swap_layouts. It isn't an issue in normal lustre builds in Centos. It hasn't been seen in routine lustre builds for sles11sp2 since those are currently client only.

I will push a trivial patch for this soon.
