There are a lot of competing implementations of live kernel patching, but work has started to agree on a common approach. As explained at http://www.linuxplumbersconf.org/2014/an-in-depth-look-live-kernel-patching-microconference/ http://www.linuxplumbersconf.org/2014/an-in-depth-look-live-... "There has been a great deal of interest in live kernel patching (see http://lwn.net/Articles/597407/ http://lwn.net/Articles/597407/) over the past few months, with several different approaches proposed, including CRIU+kexec, kGraft, and kpatch, all in addition to ksplice. This microconference will host discussions on required infrastructure (including tracing, checkpoint/restart, kexec, and live patching), along with expositions and comparisons of the various approaches. The purpose, believe it or not, is to work towards a common implementation that everyone can live with. It should be a spirited discussion!
