+autofs-5.1.8 - fix invalid tsv access
+
+From: Ian Kent <raven@themaw.net>
+
+When using the --dumpmaps option of automount(8) a SEGV can occur
+because a thread specific data variable accessed in the code hasn't
+yet been created.
+
+The thread specific data doesn't need to be set to list the maps
+so we can create the key and rely on pthread_getspecific() returning
+NULL when the value hasn't been set as this case is handled correctly.
+
+Signed-off-by: Ian Kent <raven@themaw.net>
