Why can't apply a different patch to the same target process which was already patced

[coryee]

When applying patch, libcare-ctl will return immediately if it finds that the target process was already patched, adn i cann't figure out why the sanity check is needed. I would appreciate it if somebody can explain why?

There is a patchlevel support in libcare-ctl, take a look at patchlevel tests.
