+When function evict_should_delete() returns SHOULD_DEFER_EVICTION, gh is
+never initialized, but that isn't obvious; if it did initialize gh and
+then return SHOULD_DEFER_EVICTION, gfs2_evict_inode() would fail to
+release it.  To clarify the code, change gfs2_evict_inode() to always
+check if gh needs to be released, no matter what evict_should_delete()
+returns.
