Upgrade CentOS kernel

终于耐不住要升级下kernel了,目前epel提供两个版本: kernel-lt (4.4)和kernel-ml (4.5):

  • The kernel-ml packages are built from the sources available from the “mainline stable” branch of The Linux Kernel Archives (external link). The kernel configuration is based upon the default RHEL-7 configuration with added functionality enabled as appropriate. The packages are intentionally named kernel-ml so as not to conflict with the RHEL-7 kernels and, as such, they may be installed and updated alongside the regular kernel.
  • The kernel-lt packages are built from the sources available from The Linux Kernel Archives (external link), just like the kernel-ml packages. The difference is that kernel-lt is based on a “long term support” branch and kernel-ml is based on the “mainline stable” branch.
