Hi, Russell & haojia > > Kernel text replication performance test results depend on your > workload.

Another problem is that how to verify this patches could really work on kernel? In other word, how to verify its function rather than the performance. Maybe one workable method is that adding some print-info in the kernel code to check these patches? Many thanks Yuquan
