The current position of .rss_flags field in struct rss_info causes
that fields .rsstable and .rssqueue (both 128 bytes long) crosses
cache-line boundaries. Moving it at the end properly align all fields.
Before patch:
struct rss_info {
u64 rss_flags; /* 0 8 */
u8 rsstable[128]; /* 8 128 */
/* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */
u8 rss_queue[128]; /* 136 128 */
/* --- cacheline 4 boundary (256 bytes) was 8 bytes ago --- */
u8 rss_hkey[40]; /* 264 40 */
};
After patch:
struct rss_info {
u8 rsstable[128]; /* 0 128 */
/* --- cacheline 2 boundary (128 bytes) --- */
u8 rss_queue[128]; /* 128 128 */
/* --- cacheline 4 boundary (256 bytes) --- */
u8 rss_hkey[40]; /* 256 40 */
u64 rss_flags; /* 296 8 */
};

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
