Honestly, though, I really don't understand the point with "struct inode_time". It seems like the zeroeth-order thing is to change the kernel internal version of struct timespec to have a 64-bit time... it isn't just about inodes. We then should be explicit about the external uses of time, and use accessors. -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
