Rebooting the system to install a kernel patch is a pain. In many cases, it's worse than that: the system(s) involved may have uptime constraints that rule out reboots at arbitrary times. Users faced with such issues would often welcome a way to get a high-priority patch into the kernel without taking the system down. In response to this need, the Ksplice patch set was first posted in 2008. Ksplice never made it into the mainline, though, and, after its acquisition by Oracle, it has mostly disappeared from the Linux environment. Recently, a few alternative patches offering similar functionality have been announced; now one of them, kGraft, has been posted for consideration.KGraft is the work of Jiří Kosina and Jiří Slaby, both working at SUSE. The approach they have taken is simpler than Ksplice, and lacks some of the capabilities that Ksplice offers (adding shadow members to structures, for example). On the other hand, the basic kGraft code is only a 600-line patch, and the process of applying a patch is quite a bit more lightweight, with less impact on the system.
