    xfs: remove all boilerplate defer init/finish code · c8eac49e
    Brian Foster authored
    At this point, the transaction subsystem completely manages deferred
    items internally such that the common and boilerplate
    xfs_trans_alloc() -> xfs_defer_init() -> xfs_defer_finish() ->
    xfs_trans_commit() sequence can be replaced with a simple
    transaction allocation and commit.
    
    Remove all such boilerplate deferred ops code. In doing so, we
    change each case over to use the dfops in the transaction and
    specifically eliminate:
    
    - The on-stack dfops and associated xfs_defer_init() call, as the
      internal dfops is initialized on transaction allocation.
    - xfs_bmap_finish() calls that precede a final xfs_trans_commit() of
      a transaction.
    - xfs_defer_cancel() calls in error handlers that precede a
      transaction cancel.
    
    The only deferred ops calls that remain are those that are
    non-deterministic with respect to the final commit of the associated
    transaction or are open-coded due to special handling.
