autofs-5.0.5 - mapent becomes negative during lookup
|
|
|
|
From: Ian Kent <raven@themaw.net>
|
|
|
|
During a mount request it is possible for a mapent to become negative
|
|
between the time it is checked on entry and when we fetch the mount
|
|
location information. This is because we drop the cache lock after
|
|
the initial check and take it back again before getting the location
|
|
information.
