Revert "ext4: wait on all pending commits in ext4_sync_fs()"
(cherry picked from commit 9eddacf9e9c03578ef2c07c9534423e823d677f8) This undoes commit 14ce0cb411c88681ab8f3a4c9caa7f42e97a3184. Since jbd2_journal_start_commit() is now fixed to return 1 when we started a transaction commit, there's some transaction waiting to be committed or there's a transaction already committing, we don't need to call ext4_force_commit() in ext4_sync_fs(). Furthermore ext4_force_commit() can unnecessarily create sync transaction which is expensive so it's worthwhile to remove it when we can. http://bugzilla.kernel.org/show_bug.cgi?id=12224 Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: Eric Sandeen <sandeen@redhat.com> Cc: linux-ext4@vger.kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
