X-Bugzilla-Reason: AssignedTo Mailing-List: contact systemtap-help@sourceware.org; run by ezmlm Precedence: bulk List-Subscribe: List-Post: List-Help: , Sender: systemtap-owner@sourceware.org X-SW-Source: 2006-q1/txt/msg00861.txt.bz2 ------- Additional Comments From prasanna at in dot ibm dot com 2006-03-23 04:56 ------- Jim, Earlier kprobes used a spin_lock() to serialize kprobe execution and hence to avoid deadlocks waiting for spin_lock(), kprobes section was introduced. Also this kprobes section was useful to avoid probes on other routines which caused system crash. Now since we have RCU based implementation, we need to re-evaluate if actually __kprobes section is required for all the routines used by kprobes. In such a case mark only those routines where probes on them would be unsafe.
