In some cases the "Allocate & copy" block in ffs_epfile_io() is not executed. Consequently, in such a case ffs_alloc_buffer() is never called and struct ffs_io_data is not initialized properly. This in turn leads to problems when ffs_free_buffer() is called at the end of ffs_epfile_io(). This patch uses kzalloc() instead of kmalloc() in the aio case and memset() in non-aio case to properly initialize struct ffs_io_data.

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.
