  "message": "Audit: reorganize struct audit_watch to save 8 bytes\n\npahole showed that struct audit_watch had two holes:\n\nstruct audit_watch {\n        atomic_t                   count;                /*     0     4 */\n\n        /* XXX 4 bytes hole, try to pack */\n\n        char *                     path;                 /*     8     8 */\n        dev_t                      dev;                  /*    16     4 */\n\n        /* XXX 4 bytes hole, try to pack */\n\n        long unsigned int          ino;                  /*    24     8 */\n        struct audit_parent *      parent;               /*    32     8 */\n        struct list_head           wlist;                /*    40    16 */\n        struct list_head           rules;                /*    56    16 */\n        /* --- cacheline 1 boundary (64 bytes) was 8 bytes ago --- */\n\n        /* size: 72, cachelines: 2, members: 7 */\n        /* sum members: 64, holes: 2, sum holes: 8 */\n        /* last cacheline: 8 bytes */\n};      /* definitions: 1 */\n\nby moving dev after count we save 8 bytes,  actually improving cacheline\nusage.  There are typically very few of these in the kernel so it won\u0027t be\na large savings, but it\u0027s a good thing no matter what.\n\nSigned-off-by: Eric Paris \u003ceparis@redhat.com\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n",
