The device can set the exception event bit in one of the response UPIU, for example to notify the need for urgent BKOPs operation. In such a case, the host driver calls ufshcd_exception_event_handler to handle this notification. When trying to check the exception event status (for finding the cause for the exception event), the device may be busy with additional SCSI commands handling and may not respond within the 100ms timeout. To prevent that, we need to block SCSI commands during handling of exception events and allow retransmissions of the query requests, in case of timeout.

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.
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.
