[ Upstream commit53661ded24] This partially reverts commitd2b292c3f6("scsi: qla2xxx: Enable ATIO interrupt handshake for ISP27XX") For some workloads where the host sends a batch of commands and then pauses, ATIO interrupt coalesce can cause some incoming ATIO entries to be ignored for extended periods of time, resulting in slow performance, timeouts, and aborted commands. Disable interrupt coalesce and re-enable the dedicated ATIO MSI-X interrupt.

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.
