Subject: ocfs2/trivial: Wrap ocfs2_sysfile_cluster_lock_key within define.
X-Git-Tag: v2.6.31-rc1~23^2
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d246ab307d1d003c80fe279897dea22bf52b6e41;p=pandora-kernel.git

ocfs2/trivial: Wrap ocfs2_sysfile_cluster_lock_key within define.

Actually ocfs2_sysfile_cluster_lock_key is only used if we enable
CONFIG_DEBUG_LOCK_ALLOC. Wrap it so that we can avoid a building
warning.
fs/ocfs2/sysfile.c:53: warning: ‘ocfs2_sysfile_cluster_lock_key’
defined but not used
