From f0a71eb820596bd8f6abf64beb4cb181edaa2341 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Sat, 27 Jun 2009 07:04:55 -0400 Subject: [PATCH] cifs: fix fh_mutex locking in cifs_reopen_file Fixes a regression caused by commit a6ce4932fbdbcd8f8e8c6df76812014351c32892 When this lock was converted to a mutex, the locks were turned into unlocks and vice-versa.
