Subject: [PATCH 0/2] Fix sending of a barrier and transaction waiting in ext4_sync_file()

  Hi Ted,

  the two patches below fix ext4_sync_file() to wait for a transaction commit
properly (return value of jbd2_log_start_commit() is not exactly what
ext4_sync_file() thinks it is). It also optimizes / fixes sending of a barrier
in some cases (e.g. in ordered mode with external journal we cannot really
depend on transaction commit to issue a barrier to fs device because we don't
seem to add inode to a transaction for overwrites).

I already fixed ext3 in this regard some time ago but didn't get to porting the
patches to ext4.
