Stop execution if CMD_T_STOP has been set for a command just after the command has been added to the device command list and before .write_pending() is called. The following sequence can trigger this: - transport_handle_cdb_direct() gets called. This function namely sets CMD_T_ACTIVE before it calls transport_generic_new_cmd(). - __transport_wait_for_tasks() is called concurrently. This function sets CMD_T_STOP for all active commands that have not been aborted.

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.
