H A Dcallbacks.rst5 Livepatch (un)patch-callbacks provide a mechanism for livepatch modules
10 - Safe updates to global data
12 - "Patches" to init and probe functions
14 - Patching otherwise unpatchable code (i.e. assembly)
25 - Module init/exit code doesn't run when disabling and re-enabling a
28 - A module notifier can't stop a to-be-patched module from loading.
39 * Pre-patch
40 - before a klp_object is patched
42 * Post-patch
