Ivan Vecera 646d2c10aa be2net: move txcp field in be_tx_obj to eliminate holes in the struct
Before patch:
struct be_tx_obj {
        u32                        db_offset;            /*     0     4 */

        /* XXX 4 bytes hole, try to pack */

        struct be_queue_info       q;                    /*     8    56 */
        /* --- cacheline 1 boundary (64 bytes) --- */
        struct be_queue_info       cq;                   /*    64    56 */
        struct be_tx_compl_info    txcp;                 /*   120     4 */

        /* XXX 4 bytes hole, try to pack */

        /* --- cacheline 2 boundary (128 bytes) --- */
        struct sk_buff *           sent_skb_list[2048];  /*   128 16384 */
        ...
}:

After patch:
struct be_tx_obj {
        u32                        db_offset;            /*     0     4 */
        struct be_tx_compl_info    txcp;                 /*     4     4 */
        struct be_queue_info       q;                    /*     8    56 */
        /* --- cacheline 1 boundary (64 bytes) --- */
        struct be_queue_info       cq;                   /*    64    56 */
        struct sk_buff *           sent_skb_list[2048];  /*   120 16384 */
        ...
};

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.
