It's OK as long as the 64-bit kernel, N32 and O32 userspace all agree there there's 32 bits of padding between the fields of this structure: struct epoll_event { __u32 events; __u64 data; }; I suspect it's a fairly safe bet that N32 userspace agrees; if the O32 ABI is different then it would need the compat syscall. -- dwmw2 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
