In resetting the controller, SATA devices may be lost. The issue is that when we insert the bcast events to rescan the topology in hisi_sas_rescan_topology(), when we subsequently nexus reset the SATA devices in hisi_sas_async_I_T_nexus_reset(), there is a small timing window in which the remote phy is down and we process the bcast event (meaning that libsas judges that the disk is lost). Ensure that all bcast events are processed prior to the nexus reset to close this window.

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.
