Cover letter [PATCH 0/2]: WARN_ONCE in arch/x86/kernel/hw_breakpoint.c

Quoted 6 lines · Vince Weaver

on 3.10-rc1 with the trinity fuzzer patched to exercise the perf_event_open() syscall I am triggering this WARN_ONCE:
[   75.864822] ------------[ cut here ]------------
[   75.864830] WARNING: at arch/x86/kernel/hw_breakpoint.c:121 arch_install_hw_breakpoint+0x5b/0xcb()

Ingo,

I am not sure about -stable, but probably this is 3.10 material.

Oleg.
