Revision a365a65f9ca1ceb9cf1ac29db4a4f51df7c507ad authored by Li Huafei on 10 March 2022, 12:09:15 UTC, committed by Borislav Petkov on 11 March 2022, 18:19:30 UTC
Since kprobe_int3_handler() is called in do_int3(), probing do_int3()
can cause a breakpoint recursion and crash the kernel. Therefore,
do_int3() should be marked as NOKPROBE_SYMBOL.
