    vfs_prealloc: Remove call to gpfs_prealloc
    
    Calling gpfs_prealloc changes the actual size of the file, and this
    should not be done implicitly. Also this code does not compile due to
    the missing dependency to the gpfs library. The best way solution here
    is probably removing the call to gpfs_prealloc. The vfs_gpfs module
    already implements the call to gpfs_prelloc when this can be done
    safely.
