1autofs-5.0.7 - fix wildcard multi map regression
2
3From: Ian Kent <raven@themaw.net>
4
5A recent patch that removed code to add the current map entry when
6being parsed if it didn't already exist cause wildcard indirect
7multi-mount map entries to fail to mount.
8
9Indirect multi-mount map entries need the entry matched by a wildcard
10lookup to be added to the map entry cache because subsequent operations
11expect a distinct map entry to be present or they will fail. This is
12what the code that was removed did but it did so in the wrong place
13which caused a deadlock situation.
