    Subject[18/34] ext4: fix error handling in ext4_ind_get_blocks()
    2.6.32-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    (cherry picked from commit 2bba702d4f88d7b010ec37e2527b552588404ae7)

    When an error happened in ext4_splice_branch we failed to notice that
    in ext4_ind_get_blocks and mapped the buffer anyway. Fix the problem
    by checking for error properly.
