Each worker thread can process 1 command at a time so there's no need to allocate a upages array per cmd. This patch moves it to per queue. Even a small device with 128 cmds and 1 queue this brings mem use for the array from 2 MB = 8 bytes per page pointer * 2048 pointers * 128 cmds to 16K = 8 bytes per pointer * 2048 * 1 queue Signed-off-by: Mike Christie <michael.christie@oracle.com> Message-Id: <20241203191705.19431-2-michael.christie@oracle.com> Signed-off-by: Michael S.

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.
