There was some discussion a while ago in lkml about a "more eager to blush buffers" async mode. Basically, if the system is reasonably idle and there are buffered writes, write them out without waiting the usual 5s. It makes sync virtually instant unless the system is loaded, at the expense of a bit more fragmentation (not an issue on flash, except that it may incur on a few more erasecycles). It even got a moniker, and I think I saw it an implementation either on ext3 or vfat. It was mainly thought as a good mount option for removable drives -- reducing the impact of users removing the USB disk if they see no blinking lights. And damn I can't remember the name or anything googlable about it. m -- [email protected] [email protected] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
