discard_wake and gc_wake have only two values, 0 or 1. So there is no need to use int type to store them. BTW, move discard_wake to the end of the discard_cmd_control structure. Before: - sizeof(struct discard_cmd_control): 8392 After move: - sizeof(struct discard_cmd_control): 8384 Signed-off-by: Yangtao Li <frank.li@vivo.com> Reviewed-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
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.
