[ Upstream commit 0bade8e53279157c7cc9dd95d573b7e82223d78a ]
The adapter request_limit is hardcoded to be INITIAL_SRP_LIMIT which is
currently an arbitrary value of 800. Increase this value to 1024 which
better matches the characteristics of the typical IBMi Initiator that
supports 32 LUNs and a queue depth of 32.
This change also has the secondary benefit of being a power of two as
required by the kfifo API. Since, Commit ab9bb6318b09 ("Partially revert
"kfifo: fix kfifo_alloc() and kfifo_init()"") the size of IU pool for each
target has been rounded down to 512 when attempting to kfifo_init() those
pools with the current request_limit size of 800.

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.
