Hmm, the idea seem to be patented by Microsoft, i.e. this patent from December 2002: http://www.google.com/patents?id=cVyWAAAAEBAJ&dq=hotpatching (and other patents by Microsoft if you search for "hotpatching"). And those patent descriptions, by the way, remind the way kexec works ("A software module is hotpatched by loading a patch into memory and modifying an instruction in the original module to jump to the patch"), which was released much earlier... In essence, they patented kexec ;) -- Tomasz Chmielewski http://wpkg.org
