  GFS2: Fix unsafe dereference in dump_holder() (2014-01-02 12:18:04 +0000)

----------------------------------------------------------------
Here is a set of small fixes for GFS2. There is a fix to drop
s_umount which is copied in from the core vfs, two patches
relate to a hard to hit "use after free" and memory leak.
Two patches related to using DIO and buffered I/O on the same
file to ensure correct operation in relation to glock state
changes. The final patch adds an RCU read lock to ensure
correct locking on an error path.

      GFS2: Fix use-after-free race when calling gfs2_remove_from_ail
