Thanks,

Force pushed fixed commit 660585b56e63 ("fuse: wait for writepages in
syncfs") to fuse.git#for-next.

This is fixed as far as I'm concerned, not sure how to tell that to syzbot.

Thanks -- we can let syzbot know:

#syz fix: fuse: wait for writepages in syncfs

(The syntax is just "#syz fix: <commit title>".)

Yeah, but that patch has several versions, one of which is broken.
Syzbot can't tell the difference just based on the title.

Hi Miklos,

For such cases it's useful to include Tested-by: tag into the commit
version that fixes the bug:
http://bit.do/syzbot#amend

Okay, will do that next time.

Thanks,
Miklos
