I'm seeing this in the kernel log:
kasan: CONFIG_KASAN_INLINE enabled
kasan: GPF could be caused by NULL-ptr deref or user memory accessgeneral protection fault: 0000 [#1] KASAN
CPU: 0 PID: 56 Comm: ext4.exe Not tainted 4.7.0-rc6 #1
We really ought to be using \n with pr_*() so the 'general protection
fault...' starts on a line of its own. With this patch it looks better:
kasan: CONFIG_KASAN_INLINE enabled
kasan: GPF could be caused by NULL-ptr deref or user memory access
general protection fault: 0000 [#1] KASAN
CPU: 0 PID: 56 Comm: ext4.exe Not tainted 4.7.0-rc7+ #650
