TCM always fails SBC commands with residuals for 4Kn devices when the command is processed by sbc_parse_cdb(). That prevents residual signalling to the transport driver because residual kind and residual amount aren't set. It also makes residual handling different from 512-byte formatted devices - if there are residuals 512-byte LUN would proceed with command execution while 4K-byte LUN would fail.

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.
