In v4.18-rc1, /proc/$pid/cmdline is missing final null byte which used to be there in v4.17 and older kernels:
4.17.1: tweed:~ # cat /proc/self/cmdline | od -t c 0000000 c a t \0 / p r o c / s e l f / c 0000020 m d l i n e \0 0000027
4.18-rc1: lion:~ # cat /proc/self/cmdline | od -t c 0000000 c a t \0 / p r o c / s e l f / c 0000020 m d l i n e 0000026
The code has been rewritten quite a lot in 4.18-rc1 so I didn't find yet where exactly does the change come from. Still looking.
