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.

Introduce the function scsi_cdl_check() to detect if a device supports command duration limits (CDL). Support for the READ 16, WRITE 16, READ 32 and WRITE 32 commands are checked using the function scsi_report_opcode() to probe the rwcdlp and cdlp bits as they indicate the mode page defining the command duration limits descriptors that apply to the command being tested. If any of these commands support CDL, the field cdl_supported of struct scsi_device is set to 1 to indicate that the device supports CDL. Support for CDL for a device is advertizes through sysfs using the new cdl_supported device attribute. This attribute value is 1 for a device supporting CDL and 0 otherwise.
