Well, offsets are wrong but layout OK struct fd_map { /* * read mostly part */ unsigned int base; /* 0x00 */ unsigned int size; /* 0x04 */ struct list_head slist; /* 0x08 */ struct list_head *slots; /* 0x18 */ unsigned long *map; /* 0x20 */ void (*freecb)(void *, struct fd_map *); /* 0x28 */ void *freecb_priv; /* 0x30 */ /* one 8 bytes hole */ /* * written part on a separate cache line in SMP */ unsigned int fdnext ____cacheline_aligned_in_smp; /* 0x40 */ struct fd_map *next; /* 0x48 */ struct rcu_head rcu; /* 0x50 */ }; /* size 0x60 , aligned to 0x80 */ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
