To correctly suspend-resume. We have been using this force unmount historically to circumvent the suspend-resume issues which periodically occur with fuse. We observe FUSE rejecting to remount the device because of the issue this patchset attempts to address after the resume if there are still open file handles holding old super blocks. I am not sure if fuse's interaction with suspend is something that has been resolved systematically (we are also trying to figure that out). Regardless of that, doing force unmount of a mount point is a legitimate operation, and with FUSE it may leave the system in a state that is returning errors for other legitimate operations. Thanks, Daniil
