I don't see a discussion of this anywhere ... and I thought linux-api was the right place to ask. I see holepunch as being "like ftruncate() but for the middle of the file". So it feels weird to me that MAP_PRIVATE behaves differently; truncate will rip out COWed pages, but holepunch won't. Is there a good reason for this behaviour, and is it too late to change? -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
