[PATCH v3 10/25] cifs: Change how dentry's d_lock field is accessed

From: Waiman Long
Date: Wed Jul 03 2013 - 16:21:28 EST


Because of the changes made in dcache.h header file, files that
use the d_lock field of the dentry structure need to be changed
accordingly. All the d_lock's spin_lock() and spin_unlock() calls
are replaced by the corresponding d_lock() and d_unlock() calls.
There is no change in logic and everything should just work.
