Hello,
i am in /usr/src/linux and i am trying to do:
patch -p0 < grsecurity-1.9.5-2.4.18.patch

if i do so i get that output:
can't find file to patch at input line 4
Perhaps you used the wrong -p or --strip option?

do that command from /usr/src

or alternatively:

in /usr/src/linux
patch -p1 < grsecurity-1.9.5-2.4.18.patch
