Add a timeout value to requests sent to physical devices via the RAID path. A timeout value of zero means wait indefinitely, which may cause the OS to issue Target Management Function (TMF) commands if the device does not respond. For input timeouts of 8 seconds or greater, the value sent to firmware is reduced by 3 seconds to provide an earlier firmware timeout and allow the OS additional time before timing out. This change improves timeout handling between the driver, firmware, and OS, helping to better manage device responsiveness and avoid indefinite waits.

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 reStructuredText 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.
