[ Upstream commit2a459f6933] Mask out the "Command Supported" and "Logical Block Content Change" bits and only defer execution of commands that have non-trivial effects to the workqueue for synchronous execution. This allows to execute admin commands asynchronously on controllers that provide a Command Supported and Effects log page, and will keep allowing to execute Write commands asynchronously once command effects on I/O commands are taken into account.

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.
