gfs2: Dirty source inode during rename
Mark the source inode dirty during a rename instead of just updating the underlying buffer head. Otherwise, fsync may find the inode clean and will then skip flushing the journal. A subsequent power failure will cause the rename to be lost. This happens in command sequences like: xfs_io -f -c 'pwrite 0 4096' -c 'fsync' foo mv foo bar xfs_io -c 'fsync' bar # power failure Fixes xfstests generic/322, generic/376.
