Hello. I'm getting this:
kernel/built-in.o(.text+0x68f3): In function `do_exit':
: undefined reference to `gr_shm_exit'
make: *** [.tmp_vmlinux1] Error 1
gr_shm_exit is defined from grsecurity.h, which is included in kernel/exit.c. So I don't really know what is going on here. I get this error regardless of any options I enable, if i disable grsec all together I still get this error.
