The patch titled
     Subject: autofs: remove ino free in autofs4_dir_symlink()
has been removed from the -mm tree.  Its filename was
     autofs-remove-ino-free-in-autofs4_dir_symlink.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Ian Kent <raven@themaw.net>
Subject: autofs: remove ino free in autofs4_dir_symlink()

The inode allocation failure case in autofs4_dir_symlink() frees the
autofs dentry info of the dentry without setting ->d_fsdata to NULL.

That could lead to a double free so just get rid of the free and leave it
to ->d_release().
