Yes, In fact, I reboot the whole system after I upgrade kernel. Below for your reference
[root@vs260 ~]# rpm -qa | grep kernel- kernel-tools-3.10.0-123.8.1.el7.x86_64 kernel-devel-3.10.0-123.8.1.el7.x86_64 kernel-3.10.0-123.8.1.el7.x86_64 kernel-3.10.0-123.el7.x86_64 kernel-devel-3.10.0-123.el7.x86_64 kernel-headers-3.10.0-123.8.1.el7.x86_64 kernel-debug-devel-3.10.0-123.8.1.el7.x86_64 kernel-tools-libs-3.10.0-123.8.1.el7.x86_64 The steps below: 1. Upgrade kernel 2. Reboot the system 3. Cherry-pick commit, and generate patch 4. rpm build, BTW, for you mentioned bootstrap the tree. I did not know how to do? Do you have detailed info or link I can follow? Thanks!
