Ksplice: kernel patches without reboots

Why not invalidate the patent because of prior art ?

In the eighties we had a sysadmin utility Helga on the Siemens BS2000 mainframe systems which
offered the functionality of code reps in run time. Like a process I always ran at boot time :

/EXEC      $HELGA
CHANGE X'4700',PBINIIH+BE
END

(A patch not supported by Siemens, but it worked for me.)
