It is not a big trouble yet, but keeping an obsolete patch that not very str= aightforward to figure out that it will be superseded by the panic_on_taint p= atch will only cause more confusion the longer it has stayed in linux-next. The thing is that even if you can=E2=80=99t get this panic_on_taint (the sup= erior solution) patch accepted for some reasons, someone else could still wo= rk on it until it get merged. Thus, I failed to see any possibility we will go back to the inferior soluti= on (mm-slub-add-panic_on_error-to-the-debug-facilities.patch) by all means.=
