Increase the number of reserved tags to prevent command processing failures when the driver is under stress. 8 reserved tags are quickly getting all used up leading to errors when command completions are delayed. The driver needs ~512 ccbs/tags for maximum I/O utilization: 16 (max disks) * 32 (max SATA queue depth) = ~512 ccbs/tags. By reserving 128 tags the driver will still have plenty of tags/ccbs left: 1024 (max ccbs) - 128 (reserved slot) = 896 tags/ccbs left.

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 reStructuredText 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.
