Looks almost good to me. v3 with Josh's review should be ok. Miroslav

[PATCH v2 0/1] add (un)patch callbacks
Hi folks, This is v2 of the livepatch (un)patch hook/notifier/callback/etc code. The documentation is still a little rough, but I wanted to post up the code for feedback before getting too far in revising it. This implements the pre and post handlers as Josh suggested. See summary of related changes below... v2: - s/hooks/callbacks/g - implemented pre-(un)patch and post-(un)patch callbacks - pre-patch and pre-unpatch callbacks run from callers of klp_patch_object() and klp_unpatch_object() - post-patch and post-unpatch callbacks run from klp_complete_transition() and klp_module_coming/going() - reduce callbacks from a list to a single per-klp_object instance - revamp the sample callback demo - revamp documentation Feedback appreciated as always.
