Christophe JAILLET b07490067d orangefs: Fix the size of a memory allocation in orangefs_bufmap_alloc() 
commit 40a74870b2 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.

Fixes: ea2c9c9f65 ("orangefs: bufmap rewrite")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
