Description

FileStore currently does a single fsync() to push all dirty data to disk (data=ordered(/journal?)) behavior. ext4 doesn't do that, so we need to do something else...

we could do a quick FREEZE/THAW sequence, but only if we're root.

a simple SYNCFS ioctl would be ideal...

the flush issue is resolved by using a big sync(2) hammer. sucks, but that's currently what it takes. hopefully we'll get FS_IOC_SYNCFS upstream.
