[PATCH] Reduce overhead of CONFIG_TIMER_STATS

[Arnaldo Carvalho de Melo <acme@redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 50199 bytes --]

Hi,
	While looking at the pahole output for struct timer_list on
recent kernels I noticed that there is a 4 bytes padding on struct
timer_list that gets propagated to many structs on 64 bits
architectures:

[acme@doppio linux-2.6]$ pahole -C timer_list /tmp/tcp.o.before
struct timer_list {
        struct list_head      entry;          /*     0    16 */
        long unsigned int     expires;        /*    16     8 */
        void                  (*function)(long unsigned int); /* 24     8 */
        long unsigned int     data;           /*    32     8 */
        struct tvec_t_base_s *base;           /*    40     8 */
        void *                start_site;     /*    48     8 */
        char                  start_comm[16]; /*    56    16 */
        /* --- cacheline 1 boundary (64 bytes) was 8 bytes ago --- */
        int                   start_pid;      /*    72     4 */

        /* size: 80, cachelines: 2 */
        /* padding: 4 */
        /* last cacheline: 16 bytes */
};
[acme@doppio linux-2.6]$

	So the attached patch reduces the 4 bytes hole overhead of
CONFIG_TIMER_STATS on 64bit architectures by shrinking the field for
the process name by 4 bytes.

	Statistically this doesn't affects that many process names as
most are less than 12 bytes. As CONFIG_TIMER_STATS is enabled at least
on fedora kernels I think that we can, with this patch, still reap the
benefits of powertopping.

	Results, with codiff supressing per object files per struct
reports already showed in previous object file reports:
