+autofs-5.0.6 - fix recursive mount deadlock
+
+From: Ian Kent <raven@themaw.net>
+
+Prior to the vfs-automount changes that went into 2.6.38
+and were finalized in 3.1 it was not possible to block
+path walks into multi-mounts whose root was covered by
+another mount. To deal with that a write lock was used
+to ensure the mount tree construction was completed. This
+restricts the types of recursively defined mount maps that
+can be used and can lead to a deadlock during lookup.
+
+Now that we can prevent processes walking into multi-mounts
+that are under construction we no longer need to use a
+write lock.
+
+Also, in the patch below, a cache writelock is changed to
+a read lock because a write lock isn't needed since the
+map cache entry isn't being updated.
