From 488f112297cfac795b56ddbcd7833659edba93c4 Mon Sep 17 00:00:00 2001
From: huanghua <huanghua>

Subject: [PATCH] fixed some bug during testing: (1) add osd_mksym() and
 osd_mknod() empty functions to avoid OOPS; (2) temporarily commentted out a
 sanity checking in lsm_lmm_verify_common(); (3) a small fix in
 mdt_reint_unlink().
