Christophe JAILLET e8fcfcdc9e orangefs: Fix the size of a memory allocation in orangefs_bufmap_alloc() ... commit 40a74870b2d1d3d44e13b3b73c6571dd34f5614d upstream. '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.
