I just found this list after realizing util-linux forked and writing a nearly identical patch for util-linux just yesterday to only use the blkid cache when mounting by label or uuid. I noticed your patch reads the blkid cache when guessing the filesystem type, which is the one difference from my patch. I left that out because the cost of using libblkid is almost certainly more expensive than simply using the filesystem detection logic, especially with a large number of devices. Also, that way libblkid is used for what it is intended to optimize: caching uuids and labels to prevent having to scan n**2 devices in order to mount by uuid. See my test case documented at: http://www.shapor.com/libblkid/, with a link to the thread on linux-ext4 which I cc'ed the maintainer of util-linux on with no response (yet). Its refreshing to see work being done on util-linux with an active mailing list and some issues with core Linux infrastructure being attended to. Keep up the good work!
