'buffer_index_array' really looks like a bitmap. So it should be allocated
as such.
When kzalloc is called, a number of bytes is expected, but a number of
longs is passed instead.
In get(), if not enough memory is allocated, un-allocated memory may be
read or written.
So use bitmap_zalloc() to safely allocate the correct memory size and
avoid un-expected behavior.
While at it, change the corresponding kfree() into bitmap_free() to keep
the semantic.
