I would _strongly_ suggest that if you are doing potentially high-latency USB testing CONFIG_DEBUG_VM_MAPLE_TREE is a bad thing to have enabled, as this will _massively_ increase the chances of these stalls. It's a very very heavy operation. It's good to have in ordinary testing, but for known high-latency hardware-related testing not so much. It seems always to get stuck in mas_next_slot() on mm side. Anyway... Let's re-run this against the latest pending fix tree in mm to see what happens. #syz test: git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm.git/ mm-hotfixes-unstable > Downloadable assets: >
