When I'm looking at the dashboard I can see there's another (older) reproducer which is not marked as not reproducing anymore. I suppose this is because syzbot tests only the latest reproducer? Anyway, let's close this, if syzbot can find another reproducer for the problem with writes to mounted devices disabled, it'll surely tell us :) #syz fix: fs: Block writes to mounted block devices Honza -- Jan Kara SUSE Labs, CR
