[PATCH]: reiser4 [1/8] export fsync_super()

[Nikita Danilov]

Hello, Linus,

    Following patch exports fsync_super() function. fsync_super() is
    required for reiser4, because during umount we want to perform some
    tasks after ->writepage has been called on all pages dirtied through
    mmap (that is, after fsync_super()), but before inodes
    destruction. As a result, reiser4 cannot use kill_block_super() and
    has to call fsync_super() explicitly.

Please apply.
Nikita.
