Move the security related fields above the u8s to eliminate a hole in the
struct.
pahole before:
struct ib_mad_agent {
...
u32 hi_tid; /* 48 4 */
u32 flags; /* 52 4 */
u8 port_num; /* 56 1 */
u8 rmpp_version; /* 57 1 */
/* XXX 6 bytes hole, try to pack */
/* --- cacheline 1 boundary (64 bytes) --- */
void * security; /* 64 8 */
bool smp_allowed; /* 72 1 */
bool lsm_nb_reg; /* 73 1 */
/* XXX 6 bytes hole, try to pack */
struct notifier_block lsm_nb; /* 80 24 */
/* XXX last struct has 4 bytes of padding */
/* size: 104, cachelines: 2, members: 14 */
...
};
pahole after:
struct ib_mad_agent {
...
u32 hi_tid; /* 48 4 */
u32 flags; /* 52 4 */
void * security; /* 56 8 */
/* --- cacheline 1 boundary (64 bytes) --- */
struct notifier_block lsm_nb; /* 64 24 */
/* XXX last struct has 4 bytes of padding */
u8 port_num; /* 88 1 */
u8 rmpp_version; /* 89 1 */
bool smp_allowed; /* 90 1 */
bool lsm_nb_reg; /* 91 1 */
/* size: 96, cachelines: 2, members: 14 */
...
};
