This would be a great option to improve performance of our sandbox. I can detect the availability of the new kernel API dynamically, and then not intercept the bulk of the system calls. This would allow the sandbox to work both with existing and with newer kernels. We'll post a kernel patch for discussion in the next few days, Markus _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
