Maurizio Lombardi 0787a522cc scsi: target: core: Generate correct identifiers for PR OUT transport IDs
[ Upstream commit 6e0f6aa44b68335df404a2df955055f416b5f2aa ]

Fix target_parse_pr_out_transport_id() to return a string representing
the transport ID in a human-readable format (e.g., naa.xxxxxxxx...)  for
various SCSI protocol types (SAS, FCP, SRP, SBP).

Previously, the function returned a pointer to the raw binary buffer,
which was incorrectly compared against human-readable strings, causing
comparisons to fail.  Now, the function writes a properly formatted
string into a buffer provided by the caller.  The output format depends
on the transport protocol:

* SAS: 64-bit identifier, "naa." prefix.
* FCP: 64-bit identifier, colon separated values.
* SBP: 64-bit identifier, no prefix.
* SRP: 128-bit identifier, "0x" prefix.
* iSCSI: IQN string.

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.
