Re: [PATCH] autofs4 - post expire race fix

[Jeff Moyer]

==> Regarding [PATCH] autofs4 - post expire race fix; raven@xxxxxxxxxx adds:

raven> At the tail end of an expire it's possible for a process to enter
raven> autofs4_wait, with a waitq type of NFY_NONE but find that the expire
raven> is finished. In this cause autofs4_wait will try to create a new
raven> wait but not notify the daemon leading to a hang. As the wait type
raven> is meant to delay mount requests from revalidate or lookup during an
raven> expire and the expire is done all we need to do is check if the
raven> dentry is a mountpoint. If it's not then we're done.

FWIW, this looks good to me.  (sorry for the late reply)

Thanks,

Jeff
