Subject: Umount and delegation release thread syncronization
Date: Mon, 20 Jun 2011 15:45:29 +0800 [thread overview]
Message-ID: <1308555929.3306.43.camel@perseus.themaw.net> (raw)
Hi all,
I'm having difficulty working out how delegation release threads are
synchronized with umount.
For an information about the problem please see
https://bugzilla.kernel.org/show_bug.cgi?id=30882 and in particular
comment #28.
Can someone please give me a description of the sequence of events at
umount (aka. nfs4_kill_super() function calls). In particular how does
nfs_free_server() know that if nfs_super_return_all_delegations() starts
a thread that it is finished before freeing the server struct.
Any information or observations about the opps in the above bug would
also be appreciated.
Ian
