[Cluster-devel] [PATCH] gfs2: remove redundant variable 'moved'

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

Variable 'moved' s being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'moved' set but not used [-Wunused-but-set-variable]

thanks. I've looked up since when the variable is unused and added
that info. The patch is on for-next now.
