5 Livepatch (un)patch-callbacks provide a mechanism for livepatch modules
16 In most cases, (un)patch callbacks will need to be used in conjunction
48 symmetry: pre-patch callbacks have a post-unpatch counterpart and
49 post-patch callbacks have a pre-unpatch counterpart.  An unpatch

58 callbacks will only execute if the target module is loaded.  When a
59 module target is (un)loaded, its callbacks will execute only if the
