From: Jan Kara Date: Wed, 21 May 2008 17:01:22 +0200 Subject: [PATCH] ext4: Set journal pointer to NULL when journal is released Set sbi->s_journal to NULL after we call journal_destroy(). This will be later needed because after journal_destroy() is called, ext4_clear_inode() can still be called for some inodes (e.g. root inode) and we'll need to detect there that journal doesn't exists anymore.
