Message-Id: <1215279378-30504-29-git-send-email-tytso@mit.edu> Date: Sat, 5 Jul 2008 13:35:54 -0400 From: Theodore Ts'o <tytso@....edu> To: Ext4 Developers List <linux-ext4@...r.kernel.org>, Linux Kernel Developers List <linux-kernel@...r.kernel.org> Cc: Jan Kara <jack@...e.cz>, "Theodore Ts'o" <tytso@....edu> Subject: [PATCH 28/52] ext4: Set journal pointer to NULL when journal is released From: Jan Kara <jack@...e.cz> 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.
