Thomas Falcon says: ==================== ibmvnic: Failover hardening Introduce additional transport event hardening to handle events during device reset. In the driver's current state, if a transport event is received during device reset, it can cause the device to become unresponsive as invalid operations are processed as the backing device context changes. After a transport event, the device expects a request to begin the initialization process. If the driver is still processing a previously queued device reset in this state, it is likely to fail as firmware will reject any commands other than the one to initialize the client driver's Command-Response Queue. Instead of failing and becoming dormant, the driver will make one more attempt to recover and continue operation. This is achieved by setting a state flag, which if true will direct the driver to clean up all allocated resources and perform a hard reset in an attempt to bring the driver back to an operational state. ==================== Signed-off-by: David S.

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.
