From 47b4a50bebfd34b5e1fa2a9c673c8f31fa231cc1 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Fri, 11 Jul 2008 19:27:31 -0400 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.
