autofs-5.1.4 - fix deadlock in dumpmaps
|
|
|
|
From: Ian Kent <raven@themaw.net>
|
|
|
|
Commit a223d11fa8e (autofs-5.1.3 - serialize calls to open_xxxx()
|
|
functions) introduces a deadlock when using the dumpmaps function.
|
|
|
|
In this case the open fd mutex needs to be unlocked in the forked
|
|
child process of the do_spawn() function.
|
|
