autofs-5.1.7 - reduce umount EBUSY check delay
|
|
|
|
From: Ian Kent <raven@themaw.net>
|
|
|
|
Some time ago I had to wait and retry umount() for autofs mounts
|
|
becuase I found EBUSY would be returned for a time after the call
|
|
causing false negative umount returns.
|
|
|
|
I think that problem has been resolved but removing the retry is
|
|
probably a little risky.
|
|
|
|
But the wait time is quite long at one fifth of a second so reduce
|
|
that to one twentieth of a second and increase the retries to make
|
|
it more resposive.
|
|
