From ae0dff683076b2798763288c7ac2f09a18c4a998 Mon Sep 17 00:00:00 2001 From: Sunil Mushran Date: Wed, 22 Oct 2008 13:24:29 -0700 Subject: ocfs2: Set journal descriptor to NULL after journal shutdown Patch sets journal descriptor to NULL after the journal is shutdown. This ensures that jbd2_journal_release_jbd_inode(), which removes the jbd2 inode from txn lists, can be called safely from ocfs2_clear_inode() even after the journal has been shutdown.
