We _want_ to call sys_sync() in both the hibernate and suspend paths (in case the batteries run down), to help avoid filesystem problems if something goes wrong with the resume. But it isn't a hard requirement. > > I'm not sure why this can't be made atomic, but assuming, that it > > can't, fuse should still not need to be implicated.

That's ridiculous. FUSE itself runs partially as a user task. How can you expect it to carry out a sync or anything else when it is frozen? I suppose you could "deal" with it by having the kernel portion return an error if the userspace part is frozen. If the hibernate/suspend code bothered to check the return value, it would immediately abort the suspend.
