That way the backup program will have no effect on the cache state, except for the race situation where someone read an uncached file while the backup program was reading from it too. This can be added in an hour or two with no kernel changes (use mincore). - 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/
