The RSCN_MEMENTO logic was to workaround a target that does not register
both FCP and NVMe FC4 types at the same time. This caused the
configuration to not produce a second RSCN for the NVMe FC4 type
registration in a timely manner. The intention of the RSCN_MEMENTO flag
was to always signal to try NVMe PRLI.
However, there are other FCP-only target arrays in correctly behaved
configurations that reject the NVMe PRLI followed by a LOGO leading to
never rediscovering the target after an issue_lip (as LOGO causes a repeat
of PLOGI/PRLIs).
Revert the RSCN_MEMENTO patch as it is causing correctly behaved configs to
fail while it exists only to succeed on a misbehaved config.

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.
