Dan Carpenter 18fdce809a zram: off by one in read_block_state() ... [ Upstream commit a88e03cf3d ] snprintf() returns the number of bytes it would have printed if there were space. But it does not count the NUL terminator. So that means that if "count == copied" then this has already overflowed by one character. This bug likely isn't super harmful in real life.
