From 13cfb7334eb6fd0fc06da5589aea1e947791f1d6 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 29 Sep 2010 19:51:11 -0400 Subject: cifs: have cifsFileInfo hold a reference to a tlink rather than tcon pointer cifsFileInfo needs a pointer to a tcon, but it doesn't currently hold a reference to it. Change it to keep a pointer to a tcon_link instead and hold a reference to it. That will keep the tcon from being freed until the file is closed.
