To: linux-kernel Cc: Roland McGrath , Linus Torvalds Message-ID: <200603140531_MC3-1-BAA0-B3C3@compuserve.com> MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 661 Lines: 16 I am trying to document PTRACE_SETOPTIONS and I can't figure out what the option PTRACE_O_TRACESYSGOOD is used for. Google is no help; I can't find an explanation for _why_ it's there. All I can see is that it causes ptrace() to deliver syscall stops with SIGTRAP | 0x80 instead of just SIGTRAP and it can be used with PTRACE_SYSEMU. -- Chuck "Penguins don't come from next door, they come from the Antarctic!" - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
