commit 59ac9c078141b8fd0186c0b18660a1b2c24e724e upstream.

which was broken a long time back by:
Since:
commit d81cb44726f050d7cf1be4afd9cb45d153b52066

target: go through normal processing for all zero-length commands
which moved zero-length READ and WRITE completion out of target-core,

non negative return value in fd_do_rw().

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.
