The only users of the ecc->{calc,code}_buf buffers are NAND controller
drivers implementing ecc->calculate() and/or ecc->correct(). Since the
->oobsize can be non-negligle, especially on modern NAND devices, we'd
better allocate it only when it is actually required.
Make ecc->{calc,code}_buf allocation dependent on the presence of
ecc->calculate() or ecc->correct().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
