I like the first part of the documentation, that's nice. But I don't like the new kref_get_with_check() function that you implemented. If you look in the -mm tree, kref_put() now returns if this was the last put on the reference count or not, to help with lists of objects with a kref in it. Perhaps you can use that to implement what you need instead? thanks, greg k-h - 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/
